750 miles. i'll create two functions a(m) for plan a, and b(m) for plan b. since plan a has a flat fee, plus a mileage fee, the function is: a(m) = 75 + 0.20m since plan b only has a mileage fee, it's function is: b(m) = 0.30m since we're looking for some mileage where both plans cost the same, let's set them equal to each other, then solve for m. so 75 + 0.20m = 0.30m 75 = 0.10m 750 = m so the rental fee for both plans will be equal at 750 miles.
