car rental agency a charges $50 per day plus 10 cents per mile driven. agency b charges $20 per day plus 30 cents per mile driven. when will car rental agency a be cheaper than car rental agency b for a one-day rental?

Answer 1

50 + 10m < 20 + 30m

30 < 20m

m > 1.5 miles

For a one-day rental, car rental agency a will be cheaper than car rental agency b when the number of miles driven is greater than 1.5 (1 1/2).
