Explanation:
The computation of the future value is shown below:
As we know that
Future value = Present value × (1 + interest rate)^number of years
In the first case,
Future value = $2,050 × (1 + 0.12)^12
           = $2,050 × 3.895975993
           = $7,986.75
In the second case,
Future value = $8,352 × (1 + 0.10)^6
           = $8,352 × 1.771561
           = $14,796.08
In the third case,
Future value =  $72,355× (1 + 0.11)^13
           = $72,355 × 3.883280163
           = $280,974.74
In the fourth case,
Future value = $179,796 × (1 + 0.07)^7
           = $179,796 × 1.605781476
           = $288,713.09
