Sharko earns $2160 a month. He spends $1540 every month and saves the rest. How much will he save in 5 years?

Sure, here are the steps to solve the problem:

1. First, we need to find out how much Sharko saves each month. We do this by subtracting his monthly expenses from his monthly earnings. So, $2160 (earnings) -$1540 (expenses) = $620. This means Sharko saves$620 each month.

2. Next, we need to find out how much he saves in a year. Since there are 12 months in a year, we multiply his monthly savings by 12. So, $620 x 12 =$7440. This means Sharko saves $7440 in a year.

3. Finally, we need to find out how much he saves in 5 years. We do this by multiplying his annual savings by 5. So, $7440 x 5 =$37,200.

Therefore, Sharko will save $37,200 in 5 years.
