Inaya is saving money to buy a new tablet. She already has $80 saved. Each week, she earns $15 from babysitting.
Write an equation to represent the total amount of money (M) Inaya has after (w) weeks.
If the tablet costs $200, how many weeks will it take her to afford it?
M = 15w + 80
15w+80=200
15w=120
w=8
