Deandre will have to deliver papers for another 23 weeks You get this answer by solving this equation: $380-$35/$15=23 And to make sure this is accurate u can just multiply $15 by 23 and you’ll get $345 But you have to be sure that you add the money that he already made!
If he need 380 to buy the bike but already has35, the he needs 380-35 = 345 more. if he makes 15 a week delivering papers, divide 345 by 15 to get the number of weeks it will take to save. 345/15=23 23 weeks
