Question

A car rental agency charges ​$33 per day to rent a car and ​$11.95 per day for a global positioning system​ (GPS). Customers are charged for their full tank of gas at ​$3.70 per gallon. A car has a 15 gallon tank and a GPS. ​
a) Write a function rule for the total bill b as a function of the days d the car is rented. ​
b) What is the bill for a 5 day​ rental?

Answer 1

(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

$b = (33+11.95)*5+55.5\\b=(44.95)*5+55.5\\b=224.75+55.5\\b=280.25$

The bill for a 5 day rental is $280.25
