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

$10.90

Step-by-step 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

360/29
