Alan needs a total of $290 to buy a new bicycle. He has $35 saved. He earns $15 each week delivering newspapers. How many weeks will Alan have to deliver papers to have enough money to buy the bicycle?
weeks
Let x = the number of weeks he needs to save. Since he starts with $35, that is our constant. $15 per week is our coefficient.
Therefore, 15x + 35 = 290. Now solve for x
15x = 255
x = 17 weeks
