Jack's transportation expenditures for three months were $56.08, $91.60,
and $74. What is his average monthly expense for transportation?
a. $221.68
b. $665.04
c. $73.89
d. $74
First, we need to find the total transportation expenses for the three months:
$56.08 + $91.60 + $74 = $221.68
To find the average monthly expense, we divide the total by the number of months:
$221.68 / 3 = $73.89
Therefore, the answer is c. $73.89.
