During summer vacation, you charge $15 per hour for golf lessons and a registration fee of $45. If you make $120 one day, how many hours did you spend teaching lessons? Let g represent golf lessons, write an equation for the situation.
you spend 5 hrs. first you have to substract 45 from 120 because it is a default charge. 120-45 = 75. if you divide 75 by 15 you get 5 hrs. because it 15$ per hour.
