To find Shirl's annual expense for telephone, we first need to calculate her total monthly expense for phone service and long-distance calls.
Total monthly expense = Phone service cost + Long-distance calls cost
Total monthly expense = $18.50 + $13.40
Total monthly expense = $31.90
Since there are 12 months in a year, we can calculate Shirl's annual expense for telephone by multiplying her total monthly expense by 12.
Annual expense = Total monthly expense x 12
Annual expense = $31.90 x 12
Annual expense = $382.80
Therefore, Shirl's annual expense for telephone is $382.80.
Shirl's phone service costs her $18.50 per month. If she averages
$13.40 per month for long-distance calls, what is her annual expense
for telephone?
