Lia can rent a van for either $90 per day with unlimited mileage or $50
per day with 250 free miles and an extra 25¢ for each mile over 250. For
what number of miles traveled in one day would the unlimited mileage
plan save Lia money?

Question

anonymous · Answer

90 - 50 = $40 to spend after 250 miles
Therefore 40 / .25 = 160 miles after 250 miles
So add them 250 + 160 = 410 miles

but which one saved her money?

anonymous · Answer

If she traveled 410 miles or less then she would save with the $40 car, if she traveled over 410 miles the unlimited would save her money.
