Answer: the correct answer is a. Machine B
Explanation:
Machine A average rate return
40000 out of 300000. It means that 300000 is 100% and $ 40000 is X. We apply a simple three rule:
40000       X                     X= 4000000/300000 
300000     100%               X= 13.33%
Machine B average rate return
50000 out of 250000. It means that 250000 is 100% and $ 50000 is X. We apply a simple three rule:
50000       X                     X= 5000000/250000 
250000     100%               X= 20%
Machine C average rate return
$75,000 out of $500,000. It means that $500,000 is 1005 and $75,000 is X. We apply a simple three rule
$75,000     X                       X=7500000/500000
$500,000  100%                 X= 15%
The highest average is the one onf Machine B
