Answer:

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

The formula to calculate the monthly saving is

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

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 [tex]PP \approx 0.204[/tex]
