Answer:

I was being charged for 65 miles

Step-by-step explanation:

Given

$y = 85 + 0.15x$

Required

Find x when y = 94.75

Substitute 94.75 for y in $y = 85 + 0.15x$

$94.75 = 85 + 0.15x$

Collect Like Terms

$0.15x = 94.75 - 85$

$0.15x = 9.75$

Solve for x

$x = \frac{9.75}{0.15}$

$x = 65\\$
