Tom and Isaiah have summer jobs selling newspaper subscriptions door-to-door, but their compensation plans are different. Tom earns a base wage of $11 per hour, as well as $2 for every subscription that he sells. Isaiah gets $3 per subscription sold, in addition to a base wage of $9 per hour. If they each sell a certain number of subscriptions in an hour, they will end up earning the same amount. How much would each one earn? How many subscriptions would that be?
