Question

Holden wants to earn money teaching kids how to skate. It costs him $250 to advertise his new skate school. He charges students $16 and hour to learn how to skate. How many hours does he have to teach in order to make $768, the amount needed to

buy a new gaming system?

Create an equation where r represents the
number of hours Holden needs to work.
