Problema Solution
A car rental company offers two subcompact rental plans.
Plan A: $36 per day and unlimited mileage
Plan B: $24 per day plus $0.15 per mile
Use an inequality to find the number of daily miles for which Plan A is more economical than Plan B
Answer provided by our tutors
let 'd' represent the days of rental, 'm' represent the miles driven and 'T' the total cost
Plan A:
T = 36d
Plan B:
T = 24d + 0.15m
we want to solve for 'm' such that Plan A cost is less than Plan B
36d > 24d + 0.15m
12d > 0.15m
if the rental is for one day:
12 > 0.15m
m < 80
Plan A is more economical if the number of daily miles is less than 80
