Answer:

-169

Step-by-step explanation:

We want to isolate v.

Method 1: subtract 40 from both sides, obtaining 169 = -v. Then change the sign of both sides, arriving at v = -169.

Method 2: Add v to both sides. Then v + 209 = 40.

Now subtract 209 from both sides, obtaining -169.

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

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

FV= PV*(1 + i)^n

FV= 15,000*(1.07^5)

FV= $21,038.28
