jon has to pay $7 admission for the skating rink and $1.50 per hour to rent the rollerblades. how can he skate for $19?
schepotkina [342]

H=Hours he an skate; T=total cost

T=$7.00+($1.50/hr)H

T-$7.00=($1.50/hr)H

(T-$7.00)/($1.50/hr)=H

For T=$19:

($19.00-$7.00)/($1.50/hr)=H

$12.00/($1.50/hr)=H

8hrs=H

ANSWER: Jon can skate 8 hours for $19.00.

Hope this helps!
