Rose Hill elementary school has 448 paper cups. Grade 3 uses 126 cups for a class project. Grade 2 uses 118 cups for a class picnic. Betty says that 126+118 =t cups are used in all and that 448-244=r cups are left. Is her answer reasonable. Why or why not?
Yes, her answer is reasonable because when you add 126+118, you get 244. 244 cups are used between the two classes from the original 448. So you take 448-244.
