Fatima wants to purchase a scarf for $45.00 and a sweater for &77.50. If she currently has $100, how much more money does she need to purchase the two items?
You first have to add 45 and 77.50 to see how much money she needs. You get 122.50, which you then subtract 100 from, because that's how much she has. you get 22.50, which is how much more money she needs.
