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
