The bike shop rents bikes for $5 and 5 per hour. John spends 15 dollars. How many hours did John rent the bike?

I think it is 15 hours If you wrote better I could've explained better but if that cost $5 per 5 Hour that means you spend $1 per 1 hour so if you spend $15 that mean you used bike for 15 hours

John rented the bike for 15 hours
