Answer and Explanation:

The computation is shown below:

a. The final amount she will have on deposit is

Future value = Present value * { (1 + interest rate) ^number of years - 1} : interest rate

= $11,000 * { (1 + 0.05) ^15 - 1} : 0.05

= $11,000 * 21.57856359

= $237,364.20

b. The amount at 4% is

Future value = Present value * { (1 + interest rate) ^number of years - 1} : interest rate

= $11,000 * { (1 + 0.04) ^15 - 1} : 0.04

= $11,000 * 20.02358764

= $220,259.46

c. The losing amount in case when she used her brother-in-law's bank is

= $237,364.20 - $220,259.46

= $17,104.74

We simply applied the above formula
