Question

A taxicab company charges $2.10 plus $0.80 per mile. Carmen paid a fare of $11.70. Write and solve an equation to find the number of miles she traveled.

Answer 1

y=0.8x+2.1

x= 12 miles

Explanation:

Using the standard charge of 0.8 per mile and a fixed charge of $2.1. Let x represent the miles covered then the expression for coat at any given mile will be y=0.8x+2.1

Substituting $11.7 for y then we can find the valje of x as 11.7=0.8x+2.1

0.8x=11.7-2.1=9.6

X=9.6/0.8=12 miles
