Kerri needs at least $4,800 to buy her first car. She has already saved $2,400. If she saves $50 each week, what is the minimum numbers of weeks it will take her to save for the car?
So you use x as the number of weeks and make the equation 4800=50x+2400 You then subtract 2400 on both sides to get 2400=50x Then you divide 50 on both sides to get 48=x This means she will have to work at least 48 weeks
