Set up the cost functions for Rental Truck 1 (R1) and Rental Truck 2 (R2) where m is the number of miles

R1(m) = 0.59m + 49.95

R2(m) = 0.99m + 39.95

Break even is when we set the cost functions equal to one another:

0.59m + 49.95 = 0.99m + 39.95

Typing this equation into the search engine, we get

**m = 25**.
