(a) b = (33+11.95)d + 55.5
(b) The bill for a 5 day rental is $280.25
Step-by-step explanation:
Given,
Rent of car per day = $33
Rent of GPS per day = $11.95
Cost of gas = $3.70 per gallon
Cost of 15 gallons = 3.70*15 = $55.5 per tank
a) Write a function rule for the total bill b as a function of the days d the car is rented.
Let,
d be the number of days.
Total bill = (Rent of car per day + Rent of GPS per day )* Number of days + Cost of tank
b = (33+11.95)d + 55.5
b) What is the bill for a 5 day rental?
Putting d=5 in above function
The bill for a 5 day rental is $280.25
