Jason is saving up to buy a digital camera that cost $490. So far he saves $175. He would like to buy the camera 3 weeks from now. What is the equation used to represent how much he must save every week to have enough money to purchase the camera ?
First you have to see how much more money needs to be made. Then you have to divide it by 3 because he has 3 weeks to earn the money. Then you get the answer $105 dollars a week
