300
Ms. Donnell started the week with $100. The Ninja T Shirt she bought had the price of $23.99 but she used a $5 coupon. She forgot her lunch at home and had to buy Subway, her lunch combo cost $6.75. By Friday, how much money did she have left?
What is addition and subtraction,
23.99 - 5 = $18.99
18.99 + 6.75 = 25.74
100 - 25.74 = 74.26
