Question

To rent a bicycle at the beaches there is an initial fee of $12 for each hour the bicycle is rented there's an additional $5 fee if the charge was $27 how long was the bicycle rented.

Answer 1

Initialfee+variablefee=total
initialfee=12
variaablefeet=hours times 5

total=27
27=12+5 times hours
minus 12 both sides
15=5 times hours
divide both sides by 5
3=hours

rented 3 hours
