Jamal and Herman have summer jobs selling newspaper subscriptions door-to-door, but their compensation plans are different. Jamal earns a base wage of $13 per hour, as well as $1 for
every subscription that he sells. Herman gets $2 per subscription sold, in addition to a base
wage of $5 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?
