Question

A taxicab ride costs $2.50 plus $1.10 per mile. If the total cost of the trip is $21.20, how many miles did the passenger travel? Let x represent the number of miles

Answer 1

Answer: The passenger will travel 17 miles.

Explanation:

Since we have given that

Cost of a taxicab ride = $2.50

Cost of per mile = $1.10

Total cost of the trip = $21.20

Let number of miles the passenger travel be x

According to equation,

`2.50+1.10x=\$21.20\\\\1.10x=\$21.20-\$2.50\\\\1.1x=18.7\\\\x=(18.7)/(1.1)\\\\x=17\ miles`

Hence, the passenger will travel 17 miles.
