Suppose your​ friend's parents invest 15,000 in an account paying 7% compounded annually. What will the balance be after 5 ​year
meriva

Answer:

FV= $21,038.28

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $15,000

Interest rate (i)= 7% compounded annually

Number of periods (n)= 5

<u>To calculate the future value (FV), we need to use the following formula:</u>

FV= PV*(1 + i)^n

FV= 15,000*(1.07^5)

FV= $21,038.28

Customers can pick their own pumpkins at the great pumpkin patch. They pay 4$ to enter the patch and 3$ per pound for the pumpki
klasskru [66]

Given, Customers pay $4 to enter the pumpkin patch.

And also given, customers pay $3 per pound for the pumpkins.

Given, $y be the total cost and there are x pounds of pumpkins.

The cost for pumpkin per pound = $3.

Therefore, the cost for x pound pumpkins = $(3x)

As the total cost includes the payment for entering the patch also,

So the total cost y = 3x + 4

We have got the required equation.

The equation to model the total cost is y = 3x+4.

Fiona wrote the linear equation y = 2/5 x – 5. When Henry wrote his equation, they discovered that his equation had all the same
Hoochie [10]

we have

y=\frac{2}{5}x-5

Let's Isolate the variable y in each of the cases and then compare with Fiona's equation  to determine the solution of the problem

case A) x-\frac{5}{4}y= \frac{25}{4}

Multiply by 4 both sides

4x-5y= 25

5y=4x-25

Divide by 5 both sides

y=\frac{4}{5}x-5

therefore

the case A) is not equal to Fiona's equation

case B) x-\frac{5}{2}y= \frac{25}{4}

Multiply by 4 both sides

4x-10y= 25

10y=4x-25

Divide by 10 both sides

y=\frac{2}{5}x-2.5

therefore

the case B) is not equal to Fiona's equation

case C) x-\frac{5}{4}y= \frac{25}{2}

Multiply by 4 both sides

4x-5y= 50

5y=4x-50

Divide by 5 both sides

y=\frac{4}{5}x-10

therefore

the case C) is not equal to Fiona's equation

case D) x-\frac{5}{2}y= \frac{25}{2}

Multiply by 2 both sides

2x-5y= 25

5y=2x-25

Divide by 5 both sides

y=\frac{2}{5}x-5

therefore

the case D) is  equal to Fiona's equation

<u>the answer is</u>

x-\frac{5}{2}y= \frac{25}{2}
