totsakans bike shop rents bikes for $15 plus $7 per hour. Ming paid $50 to rent a bike. for how many hours did she rent the bike?

Respuesta :

Answer:

5 hours

Step-by-step explanation:

Set up an equation where y=total cost and x= hours

y=7x+15

Substitute 50 for y, the total cost, and solve for x, the total hours

50=7x+15, Subtract 15 from both sides

35=7x, Divide both sides by 7 to get x alone

x=5
