Question

Stavros and Eyad have $45 left for a cab fare. The cab is $3 per mile plus a $1.50 fixed charge. What is the maximum number of whole miles they will be able to travel in the cab

Answer 1

I think the answer is 10 miles.

Explanation:

$3+1.50 = cab charges

$4.5

`4.5 * 10 = 45`

this method is used to cross-check that you are getting the right answer.

alternative method:-

$4.5 = cab charges

$45 = their money

`45 / 4.5 = 10`

10 miles

Answer 2

With the amount of $ 45 they will be able to travel 14.5 miles.

Explanation:

Given,

They have left with $ 45

The cab charges $ 3 per mile and $ 1.50 as fixed charge.

To find the maximum distance they will be able to travel.

Solution:

After paying the fixed charge they will be left with $(45-1.50) = $ 43.5

The charge of the cab = $ 3 per mile

By $ 43.5 they can travel = 43.5÷ 3 mile = 14.5 mile

Hence,

With the amount of $ 45 they will be able to travel 14.5 miles.
