What is compound interest?
Compound interest, also known as interest on principal and interest, is the adding of interest to the principal amount of a loan or deposit. It occurs when interest is reinvested, or added to the loaned capital rather than paid out, or when the borrower is required to pay it, so that interest is generated the next period on the principal amount plus any accumulated interest. In finance and economics, compound interest is common.
In contrast to simple interest, which does not compound since past interest is not added to the principal for the current period, compound interest allows interest to build over time. The interest per period multiplied by the number of periods in a year yields the simple annual interest rate.

Years Cashflows [email protected] 12% PV
1 5000 0.892857143 4,464.29
2 5300 0.797193878 4,225.13
3 6000 0.711780248 4,270.68
Total of present values 12,960.09

Answer:
The store manager must decide to buy 3
Explanation:
Given that:
- The first: $200 a year
- The second $150
- The third $75,
- The fourth $50
- Interest rate is 12 percent
- Investment: $500
As we know that the rate of return will be: Income / Investment
So the rate of return of:
- The first: $200 / $500 = 0.4 = 40%
- The second $150 / $500 = 0,3 = 30%
- The third $75 / $500 = 0.15 = 15%
- The fourth $50 / $500 = 0.1 = 10%
Only three rug cleaners have the rate of return greater than the interest rate so the store manager must decide to buy 3
