so if she already has $56 and she needs $268 more to buy the phone so we'll do 268 divided by 20 to see how many weeks it will take which is 13.4 so you can either put 13.4 as the answer or you can put about two weeks because there are 7 days in a week and 13.4/7 is ~1.9 or 2
23.8% of 164 is 39.032 so minus that off of 164 and you would've sold 124.968 cars and im guessing you should round so the dealership would've sold 125 cars.
