Rental A charges:
Rate per hour = $4.50
Rate for x hours = 4.50x

Rental B charges:
Rate per hour = $ 5
Rate for x hours = 5x
Equation: 12.50 + 5x

Incorrect. 1 solution.
Mark is incorrect because to find x from 8x=48 you must perform the following steps:
Divide the 8 from both sides resulting in
x=6
27) x>-6
28) x <7
29) x<= -6
30) x < 7
31) x>=-6
32) x>4
33) x > 8
34) x < 4
35 x >= 5
