Question

Ben and his friend share a taxi to work. The taxi driver charges a $2.50 flat fee as well as $0.40 for every 1/5 of a mile traveled. The total distance of the taxi ride was 4.2 miles. Ben and his friend split the final bill. How much did each friend pay?

A-$5.45
B-$10.90
C-$4.18
D-$6.70

Answer 1

$10.90

Explanation:

The total charge for the ride was C(x) = $2.50 + ($0.40 / fifth of a mile)

4.2 miles is divisible by 1/5 mile: it's the same as (4.2 mile) / 0.2 mile:

4.2 miles

--------------- = 21 This means the ride consisted of 21 1/5-mile distances.

0.2 mile

Thus,

The total charge for the ride was C(21) = $2.50 + ($0.40 / fifth of a mile)(21), or

c(21) = $2.50 + 21($0.40)

= $2.50 + $8.40

= $10.90
