Mrs. Bonse bought a box of erasers. The box had 5 different shapes of erasers. There were 8 of each shape of eraser in the box.
Mrs. Bonse gave the box of erasers to a group of 4 students to share equally. Part A: One student, Brianne, said the box contained exactly 45 total erasers. Is Brianne correct? Write an equation and draw a model to explain why or why not. Part B: Another student, Gail, said each student in the group will get exactly 10 erasers. Is Gail correct? Write an equation and draw a model to explain why or why not.
If there are 5 different shaped erasers and 8 of each, you would have to multiply which equals 40. If there are 4 people in the group, 40 divided by 10 equals 4.
