Answer:

(15+3d)/6 = c

2 1/2 + 1/2d = c     (more simplified)

Step-by-step explanation:

15 = -3(2c +d)

15 = -6c -3d

+3d       +3d

15 +3d = -6c

/-6          /-6

(15+3d)/6 = c

2 1/2 + 1/2d = c

cody's Bikes rents bikes for $18 plus $5 per hour. Mark paid $48 to rent a bike. For how many hours did he rent the bike.
kkurt [141]
He rented the bike for 6 hours. If Cody charges an 18 dollar fee up front you subtract that from the total 48 to get 30. Then once you get down to the what he payed for the time used you divide it by 5 because that’s the hourly fee and get 6 hours
