Susan and Jayne have part-time jobs selling tickets at the theater. This week, Jayne's paycheck was twice the amount of Susan's paycheck. They both were paid $7.50 an hour, and Jayne's paycheck was $60. How many hours did Susan work this week?

4 hours

Step-by-step explanation:

So if Jayne worked twice the amount of susans paycheck, it would be 60/2..so 30 is how much Susan has in her paycheck

Then you would divide both amounts by 7.50 because that’s how much they earn in a hour

J = 60/7.50 = 8 hours

S = 30/7.50 = 4 hours

Susan worked 4 hours

the answer is:

mean: 6

mad: 2.14
