According to economists, her opportunity cost of consuming caramel-coated popcorn would be the forgone peanut butter pretzels.
Opportunity costs are the possible advantages that a person, investor, or company forgoes while deciding between two options. Opportunity costs are by definition invisible, making it simple to ignore them.
Better choices can be made by being aware of the opportunities that might be lost when a company or person chooses one investment over another. It is necessary to weigh the advantages and disadvantages of each choice offered in order to correctly assess opportunity costs.

Bobs gift shop sold a record number of cards for Mother’s Day. One salesman sold 36 cards, which was 4% of the cards sold for Mother’s Day. How many cards were sold for Mother’s Day
The number of cards were sold for mother's day is 900 cards.
How to calculate total number using percentage?To calculate a total number using a percentage, first identify the percentage and the total number. Then divide the percentage by 100 to convert it to a decimal fraction. Finally, multiply the total number by the decimal fraction to calculate the total number.
For example, if the percentage is 10% and the total number is 200, first divide 10% by 100 to get 0.1. Then multiply 0.1 by 200 to get 20. The total number is 20.
In another example, if the percentage is 25% and the total number is 500, divide 25% by 100 to get 0.25. Then multiply 0.25 by 500 to get 125. The total number is 125.
It is important to remember that percentages are based on a whole, which is usually 100. Therefore, to use percentages to calculate a total number, it is necessary to first convert the percentage to a decimal fraction by dividing it by 100. Then, multiply the total number by the decimal fraction to calculate the total number.
36 cards is 4% of the total cards sold for Mother's Day.
Total number of cards = 36 / 4%
Total number of cards = 36 x 100/4
Total number of cards = 900 cards.

John is starting a roofing business. He will need to buy a truck and some supplies to get his business going. The truck costs $13000 used. He gets three jobs right away. And hires 2 workers to help him. The materials for all three jobs cost $3000 total. The jobs will each take a week not including Saturday and Sunday and he pays his workers $125 per day per worker. How much will he have to charge for each job in order to break even at the end of the third job?
As per the unitary method, the charge for each job in order to break even at the end of the third job is $3,000
In math the term unitary method is known as a single unit and then multiply the value of a single unit to the number of units to get the necessary value.
Here we have given that John is starting a roofing business. He will need to buy a truck and some supplies to get his business going.

How to determine the distance PRThe complete question is added as an attachment
From the question, we have the following parameters that can be used in our computation:
The equivalent ratio represented as
PR : 125 = PR + 170 : 245
Express the ratio as a fraction
So, we have the following representation
PR/125 = (PR + 170)/245
Cross multiply
This gives
245PR = 125PR + 21250
Evaluate the like terms
120PR = 21250
Divide both sides by 120
PR = 177

According to the given information we are trying to find the smallest time interval at which both the lighthouses will flash together.The first lighthouse flashes every 15 minutes, and the second lighthouse flashes every 18 minutes.
To find the LCM of 15 and 18, we can list out the multiples of each number and find the smallest multiple that is common to both.

solve the equation:(x+5)^4 = 81
Answer:4√81=±3
Step-by-step explanation:
If (x+5)^4 = 81,
then (x+5)^2 = ± sqrt(81), so
(x+5)^2 = ±9
Focusing on (x+5)^2 = 9 for the two real roots, we have
(x+5)^2 = 9
x+5 = ± sqrt(9)
x+5 = ± 3
x+5 = 3 gives you x = -2
x+5 = -3 gives you x = -8
There are two complex roots too, but I'm not sure if you're studying that too. If so, then you'd solve (x+5)^2 = -9:
x+5 = ± sqrt(-9)
x+5 = ±3i
x = 5 ± 3i as the two complex roots.

The approximate area (shaded region) of the remaining portion of the circle in square feet is 55.94 ft².
We know that,
the side of square=2*[r*√2/2]=r*√2 that is being taken out.
diameter = 14 ft and radius , r = 7 ft.
the side of square=7*√2=9.89 ft
[area of the remaining portion of the circle]=[ area of a circle]-[area of a square]
[area of a square] = (7√2)²=98 ft²
[ area of a circle] = π*r²= π x 7^2 = 153.94 ft²

that is a square-based prism. What is
the volume of empty space in the box?
Radius 8 cm

The volume of empty space in the box will be 220cm³
The diameter of the candle is equal to the width of the box (the length of the side of the square base of the box), and the height of the box is equal to the height of the candle, assuming that the candle fits tightly inside the box without wasting any room.
You may compute the prism's volume by multiplying it by the square base's area (height).
The area of the circular base can be used to compute the volume of the candle's cylinder (height).
The square box base's side measures 8 cm long, hence its area is equal to that measurement= 8cm²=64cm²
The candle's diameter is two times its radius, hence the radius is 8cm/2=4cm
area of the circular base thus Equals (A = π r²).

The Students Athletes Club has a monthly budget ofxdollars. Every month $500 is spent on transportation. One-fourth the remaining budget is spent on monthly activities. Which function can be used to find the amount in dollars spent on monthly activities?
The function to find the amount in dollars spent on monthly activities can be represented as: A(x) = (x - 500) * 1/4
Let x be the total monthly budget in dollars and A(x) be the function of x that determines the amount in dollars spent on monthly activities.
To find the value of A(x), we follow the steps:
First, we subtract the fixed monthly transportation cost of $500 from the total budget.
The remaining budget is then divided by 4 to find the amount spent on monthly activities.
Therefore, the function A(x) can be written as: A(x)= (x-500)/4
Thus, the function (x - 500) * 1/4 can be used to find the amount in dollars spent on monthly activities.
