C(d) = 35.95 + 0.67 d
is fine
if d = 74
C = 35.95 + 0.67 * 74
90 = 35.95 + 0.67 d
so
d = (90.00 - 35.95) / 0.67
A moving truck rental company charges $35.95 to rent a truck, plus $0.67 per mile. Suppose the function
C
(
d
)
C(d)
gives the total cost of renting the truck for one day if you drive
d
d
miles.
State the formula for
C
(
d
)
C(d)
. Make sure to give the complete formula as an equation.
C

Use function notation to give the total rental cost if you drive the truck 74 miles. Give the function notation in the first box, the answer in the second box (rounded to one decimal place), and choose the correct units from the third box.
