Jackie had $200 in savings and started working at In-n-Out for $15/hour. Her manager, Melanie, earned $20/hour, but only had $50 in savings.
Write a system equations to represent the total amount of money, y, Jackie and Melanie have after x number of hours.
In how many hours will they have the same amount of money?
Jackie: y=15x+200
Melanie: y=20x+50
They will have the same amount of money after working 30 hours.
