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.

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.
