Julie's parents' 25th anniversary is in 2 years. She'd like to give her parents a vacation package for their anniversary. She anticipates the vacation package will cost her $2000. An account at her bank pays 5% per year compounded monthly. How much does she need to deposit today in this account, so that she can buy the package deal for her parents' anniversary?
a) Simple Interest
b) Future Value with compound interest
c) Future Value with simple interest
d) Effective Rate
e) Present Value with compound interest

Answers

Answer:

e) Present Value with compound interest

Step-by-step explanation:

in order to determine how much money does Julie need to deposit we have to use the present value formula with compound interest:

present value = future value / (1 + i/12)ⁿ

future value = $2,000i/12 = 5%/12 = 0.4167%n = 24

$2,000 = present value x (1 + 0.4167%)²⁴

present value = $2,000 / (1 + 0.4167%)ⁿ = $1,810.05

you can also calculate it using the future value formula, but you will end with the present value formula:

future value = present value x (1 + i/12)ⁿ

present value = future value / (1 + i/12)ⁿ ⇒ you are adding 1 more step

you could also calculate it using the present value formula and the effective annual rate:

effective rate = (1 + 0.05/12)¹² - 1 = 5.1162%

present value = $2,000 / (1 + 5.1162)² = $1,810.05 ⇒ but again you are just adding more steps into the process

Adam, Barry, and Charles visited a small farmers market last Saturday. Adam purchased 3 dozen eggs, 1 wheel of cheese, and 5 pounds of potatoes. Barry bought 1 dozen eggs and 10 pounds of potatoes, while Charles purchased 2 dozen eggs and 2 pounds of potatoes. If Adam’s bill was $38.25, Barry’s $36.50 and Charles’ $17.20, how much did a dozen eggs, a wheel of cheese and a pound of potatoes cost?

Answers

Answer:

Dozen eggs = $5.5

Wheel of cheese = $6.25

Pound of potatoes = $3.1

Step-by-step explanation:

Let the cost

Dozen of egg = x

Wheel of cheese = y

Pound of potato = z

We will form linear equations using the information given in the question

Adam purchased 3 dozen eggs, 1 wheel of cheese, and 5 pounds of potatoes

3x + y + 5z = 38.25 ................(1)

Barry bought 1 dozen eggs and 10 pounds of potatoes

x + 10z = 36.50 ............(2)

Charles purchased 2 dozen eggs and 2 pounds of potatoes

2x + 2z = 17.20  .................(3)

solving 2 and 3

x = $5.5  and z = $3.1

substitute these values in equation 1

we get

y = $6.25

The cost

Dozen eggs = $5.5

Wheel of cheese = $6.25

Pound of potatoes = $3.1

Last year, a 1.6-gallon container of ice cream sold for $5.99. This year, the same ice cream, now in a 1.2-gallon container, sells for the same price of $5.99. By what percentage was the weight of a container of the ice cream reduced? A. 75% B. 25% C. 60% D. 40%​

Answers

Answer:

25% is the answer

Step-by-step explanation:

From last year to this year, the weight of the container is reduced by  

B. 25%

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, Last year, a 1.6-gallon container of ice cream sold for $5.99. This year, the same ice cream is now in a 1.2-gallon container.

So, The amount of icecream increased this year is,

= (1.6 - 1.2) gallons.

= 0.4 gallons.

Now to obtain percentage change we'll divide the net amount change by the original amount and multiply it by 100% which is,

= (0.4/1.6)×100%.

= 0.25×100%.

= 25%.

What are the domain and range of the function represented by the set of
ordered pairs?
{(-6, 12).(-3,-2), (1,0), (14,-4)}

Answers

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Domain = { -6 , -3 , 1 , 14 }

Range = { -4 , -2 , 0 , 12 }

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Thus the correct answer is (( B )) .

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Here, the domain and range of the function represented by the set of ordered pairs {(-6, 12).(-3,-2), (1,0), (14,-4)} is

{-6, -3, 1, 14} and {12, -2, 0, -4} respectively.

What is range?

We know that the range refers to all possible values of y, and the domain refers to all possible values of x.

How to solve it?

For (-6, 12), the x value = -6 and the y value = 12.

For (-3, -2), the x value = -3 and the y value = -2.

For (1, 0), the x value = 1 and the y value = 0.

For (14, -4), the x value = 14 and the y value = -4.

So, the domain is {-6, -3, 1, 14} and the range is {12, -2, 0, -4}.

Therefore the domain and range of the function represented by the set of ordered pairs {(-6, 12).(-3,-2), (1,0), (14,-4)} is

{-6, -3, 1, 14} and {12, -2, 0, -4} respectively. So, option B is correct.
