19. Amanda bought a 6-cup bag of shredded cheese for $6.89. She used 2.25 cups to make lasagna and 1.25 cups to make pizza. How much cheese is left?​

2.50

Step-by-step explanation:

ok, so we start out with a 6 cup bag of cheese. But then she uses 2.25 cups to make lasgna, and 1.25 cups to make pizza. we need to see how much cheese is left after she used the cups. First lets add the 2 cups: 1.25 + 2.25. Lets first add 1 + 2 = 3, then .25 + .25 = .50. Lets now add 3, and .50, and that gives us 3.50. Now to see how much cheese is left, we must subtract 6 minus 3.50, which gives us a total of 2.50. I hope that helped!
