Question

A cab company charges a $11 boarding fee and a meter rate of $2 per mile. The equation is y = 2x + 11 where x represents the number of miles to your destination. If you traveled 5 miles to your destination, how much would your total cab fee be?

Answer 1

We are given a function, y = 2x + 11, where x is the number of miles driven. If we are told that the cab was driven 5 miles, x = 5. So, substitute 5 for x.

y = 2x + 11
= 2(5) + 11
= 10 + 11
= 21
y = 21
