A class ring cost $260.00. Lewis has $80.00 in a saving account and earns $20.00 a week babysitting. Write an equation to represent the number of weeks lewis needs to work in order to purchase the ring?

The equation to represent the number of weeks Lewis needs to work in order to purchase the rings is as follows, y=20x+80. y is the cost of the ring, 20 is how much he gets, x, weeks. 80 is the initial value, the money he already has. Using the equation we can plug y with 260, 260=20x+80. To solve this equation you subtract 80 from each side, 260-80=20x+80-80 which simplified is 180=20x. Then you divide 20 into each side to isolate the variable. 180/20=20x/20 which simplified is 9=x. The answer is, "It will take 9 weeks for Lewis to purchase the ring."

Pretty sure it’s (260-80) divided by 20
