Question 299306: suppose you rent a car for $21 per day and 15 cents per mile. How many miles could you have driven for a rental charge of $51?

Let x = the number of miles driven.
The rental charge can be expressed as:
C = $21+$0.15x and for C = $51.00 you get:
51 = 21+0.15x Subtract 21 from both sides.
30 = 0.15x Divide both sides by 0.15
x = 200 miles. This assumes these miles were driven in a single day.
