$,2884 |
b |
$14,130.23 |
c |
$2,826.05 |
d |
$2,403.33 |
Option c $2,826.05 is the correct answer.
Explanation:
Average Medical Expense of April = 1.7 * Medical Expense of February
= 1.7 * $2,657 = $4,516.90
Average Medical Expense of May = ( Medical Expense of January + Medical Expense of Feb + Medical Expense of March) / 3 Years
= ($2,195 + $2,657 + $2,358) / 3 = $2403.33
Hence, Williams’ average monthly expenditure for January through May = ( Medical Expense of January + Medical Expense of Feb + Medical Expense of March + Medical Expense of April + Medical Expense of May) / 5 Years
= ($2,195 + $2,657 + $2,358 + $2,403.33 + $4,516.90) / 5 = $2,826.05
