Billy borrowed $400 from his friend Tommy to get his truck fixed. The next time he got paid, Billy paid Tommy back $100, then agreed to pay $25 a week until his debt was paid off. 1.Write a linear equation to represent the amount of money m Billy owes Tommy after w weeks. 2.How long will it take Billy to pay off his debt to Tommy?
Billy gives Tommy 100, so we can subtract $100 from $400, giving us 300. Then to undertand how many weeks it will take Billie to pay Tommy, we divide 300 by 25, and get 12.
