Question

The function y = 33.50x +40 is used to
find the cost of renting a car. Where x
represents the number of days you rent
the car. How much would it cost to rent
a car for 3 weeks

Answer 1

3 weeks * 7 days / 1 week = 21 days
Substitute 21 into the equation
y = 33.50(21) + 40
y = 743.5

Therefore, it would cost $743.50 to rent the car for 3 weeks
