Ace Rent a Car charges a flat fee of $15 and $0.25 a mile for their cars. Acme Rent a Car charges a flat fee of $30 and $0.17 a mile for their cars. Use the following model to find out after how many miles Ace Rent a Car becomes more expensive than Acme Rent a Car. c= 15+0.25m Ace, c=30+0.17m Acme

Would someone please help me?

Answer 1

so
15 + .25 m = 30 + .17 m

.08 m = 15

m = 1500/8

m = 187.5 miles

Answer 2

.08m = 15 = 08m/.08 = 15/.08(m) = m =187.5

Answer 3

15+ .25(187.5) = 30+.17(187.5)
15 + 46.875 = 30 + 31.875 =
61.875 = 61.875 miles
