Question

Mears Taxi charges a $ 3.95 flat rate for a ride in the cab. In addition to that, they charge $ 0.75 per mile. Katie has no more than $ 16 to spend on a ride. At most, how many miles can Katie travel without exceeding her spending limit?

Answer 1

About 16 miles

The equation:

.75x+3.95

At 16 miles Katie will have spent $15.95.

Answer 2

16 miles

Explanation:

3.95 + .75m < 16

Subtract 3.95 from each side

3.95 -3.95+ .75m < 16-3.95

.75m < 12.05

Divide each side by .75

.75m/.75 < 12.05/.75

m <16.066666666

Rounding to the nearest mile

m < 16
