The price of an item decreased by 10% each week for 4 weeks. What was the approximate percent of decrease of the price of the item after 4 weeks?
A 34%
B 40%
C 60%
D 66%
Answer:
34%
Step-by-step explanation:
Answer:
A) 34%
Step-by-step explanation:
Lets say that the price of this object was $100.
Then, we know that each week the price is reducing by 10%, so therefore, we take 10% of $100, and we have $10
If we subtract that from $100, ($100-$10), we find that the price has come down to $90 after the first reduction in the first week. We will now do this process three more times to get to the four weeks total.
10% of $90 dollars is 9 dollars, so therefore the price reduces to $90-$9, $81 after the second reduction in the second week.
Then we take 10% of $81 and then get $8.1. We subtract that from $81 and get $72.9
Then for the final reduction in the fourth week, we take 10% of $72.9, and we get $7.29. Take that from $72.9, and you get $65.61, which we can round to $66.
The question however asks how much was the approximate percantage in decresse over the 4 weeks. We see that the object went from $100 to $66, which is $34 decrease.
Now we simply find what percantage of $100 is $34, and that is 34%, which gives you option A.
Hope this helped.

aria and her two friends met up for dinner. They want to split the cost of dinner evenly between the friends but first had to get the total after adding the tax and tip. Their bill is shown below. The sales tax at this location of Sam’s World is 7.75%. They agreed to leave an 20% tip. The tip is added to the total after the sales tax is added.
The total is 38.96
Estimate the approximate total cost of the bill including tax and tip to the nearest dollar.
A
$50.38
B
$41.98
C
$38.96
D
$8.40
PLEASE HELp
Answer:
A. 50.38
Step-by-step explanation:
Bill is 38.96. Calculate sales tax: 38.96x.0775=3.02.
38.96 + 3.02=41.98 total before tip
41.98x.20=8.40 tip
41.98 + 8.40=50.38

Answer:
blue line : y = 3
black horizontal line : y = 0
black vertical line : x = 0
Step-by-step explanation:
it is really simple.
blue line : no matter what value we pick for x, the functional value for y is always 3. and that defines the equation y = 3 + 0*x or simply y = 3.
the same with the black horizontal line. the difference is that y is now always 0. so, y = 0.

Each bag of pears weighs 1 kg 160 gram. What is total weight of a sack which contains 5 bags of pears?
Answer:
5 kg 800 grams
5800g
Step-by-step explanation:
the first step is to convert 1kg to gram
100 kilogram = 1 gram
1kg x 1000 = 1000g
1kg 160 gram = 1000 + 160 = 1160 gram
If 1 sack weighs 1160 g
5 sacks = 1160g x 5 = 5800 gram
or 5800 / 1000 = 5 kg 800 grams

-4 (y - 2) = 12
Answer:
y = -1
Step-by-step explanation:
I'll solve for "y" since there is no "x"
First expand the numbers inside the parenthesis by multiplying -4
-4y + 8 =12
Subtract 8 from both sides to isolate -4y
-4y = 4
divide both sides by -4 to get "y"
y= -1
Lol i dont know
ANSWER:y = -1Solution:-4(y - 2) = 12= y - 2 = -3= y = -1hehe
please help me...?
i'll give brainliest to correct answer! :D
Answer:
D) 100% Positve
Step-by-step explanation:
You would choose the second option (y=1/3x) because the slope would be 1/3. Think of the slope as your directions, you go up 1 over to the right 3 times. Since the y-intercept is 0, you don't have to add anything at the end.
Hope this answer makes sense.

A convergent infinite geometric series, the graph of the series curves away from the sum, the correct option is B.
What is a Geometric Series?A sequence of numbers such that the consecutive term is increasing or decreasing by a fixed ratio is called a geometric series.
The standard equation for geometric series is
Tₙ = a₁ rⁿ⁻¹
The sum of an infinite geometric series is given by
S = a₁/(1-r)
where a₁ is the first term and r is the common ratio.
The graph of an infinite series curves away from its sum.

Paula has her own business making cakes for
special occasions. The total price (p) of one
of Paula’s cakes is represented by the equation
p=0.75s +10 , where s is the number of
people the cake serves. What does the .75
represent in this situation and what does the 10 represent in this equation?
Answer:
Since Paula has her own business of making cakes for special occasions, and the total price (P) of one of Paula's cakes is represented by the equation P = 0.75S +10, where S is the number of people the cake serves, for determine what does the 0.75 represent in this situation and what does the 10 represent in this equation, the following mathematical reasoning must be carried out:
P is the price of the cake
S is the number of servings
Therefore, 0.75 is the value of each serving, which can be variable (the number of servings can vary)
In turn, 10 is the fixed cost of each cake.
surface area of sphere round to the nearest tenth
Answer:
804.2
Step-by-step explanation:
what ? you cannot use a calculator ? it is all there, you only need to type it in.
the only point, where you need to "think" is the difference between radius and diameter. because the graphic gave you the diameter, and the formula asks for the radius.
so ... ... ... ... did you figure it out ?
the radius is half of the diameter, so, 8ft in this example.
S.A. stands for "Surface Area".
so, now, again, we only need to type it into the calculator.

The solution is, the letters in the word GRADE can be arranged in 120 ways.
What is combination?In mathematics, a combination is a selection of items from a set that has distinct members, such that the order of selection does not matter.
here, we have,
Given that we are to evaluate the number of ways to arrange the letters in the word GRADE,
In the word GRADE, we have 5 distinct letters:
G(1), R(2), A(3), D(4), E(5).
There are 5 letters.
Thus, the number of ways of arranging the letters is evaluated as
5! = 1×2×3×4×5
=120
Hence, the letters in the word GRADE can be arranged in 120 ways.
