Answer:
38.13 = 12 +4.75h
5.5 hours
Step-by-step explanation:
(a) The charge (c) for renting a bike for h hours is ...
c = helmet charge + hourly charge × hours
c = 12.00 +4.75h
To find the number of hours when the charge is 38.13, we would use the equation ...
38.13 = 12.00 +4.75h
__
(b) To solve this 2-step linear equation, we first subtract the constant
26.13 = 4.75h
then we divide by the coefficient of the variable.
26.13/4.75 = h ≈ 5.5
Amanda rented the bike for 5.5 hours.

<em>Additional comment</em>
The result of the division is a long repeating decimal that starts off 5.50105263.... The instructions tell you to round this to the nearest tenth: 5.5. It helps to follow instructions.
The answer is 1/9, because 2/3 divided by 6 equals 1/9.
Hope this helps!
