Acompany will need $45000 in 5 years for a new addition. to meet this goal, the company deposits money in an account today that pays 7% annual interest compounded quarterly. find the amount that should be invested to total $45,000 in 5 years?

The general formula is
A = P ( 1 + 

Where:
P = principal that becomes A in t years at the rate I% compound interest per annum.

Here the rate is 7% per annum (12 months)
So I is 1.75% per quarter (3 months)
So t will also be in quarters.

Put:
A = 45000
I = 1.75
t = 20 (since there are 20 quarters in 5 years)(5 years * 4 quarters per year)

45000 = P* 
P = 
= 
≈$31807.12

Thus, the amount that should be invested is $31,807.12

Okay so it will be 1123
