56 would be the answer.

WAIT, don’t leave just yet! You have to show at least some work! You CANT learn if you don’t know what you’re doing.

Here’s how I got the answer:

M = (7/4) / (10/8) x 40
M = 56 minutes.

If that helped let me know by hitting the thanks button or reply with any help you need.

Have a FABULOUS DAYYY!

Your goal is to create a college fund for your child. Suppose you find a fund that offers an APR of 7 %. How much should you dep

Yanka [14]

Answer:

You shoud invest $0.204, it is an small amount each month.

The formula to calculate the monthly saving is

$PP= \frac{A(APR/n)}{(1+(APR/n))^{nY}-1}$

with PP: periodic payments, A: amount desired, n: number of payments in one year, Y: number of years.

In this case A = 88, n= 12 (the payments are monthly), Y=18, APR=7%.

Replacing in the formula you obtain that $PP \approx 0.204$
