Your teacher wants you to help her get organized for when the cups arrive next week. Using only the information shown in the picture, she asks you to figure out some other specific measurements.

3.

Your teacher thinks that instead of having to figure out these stacks each time, it would be useful to understand the general relationship.
Write an equation expressing the relationship between the height of the stack and the number of cups in the stack.
Let h represent the height of the stack, in cm, and n the number of cups in the stack.

The catalog is advertising a stack of these cups that is 95 cm tall. Lori says, "That must be a misprint because a stack of that height is not possible."
Do you agree or disagree with Lori? Explain your reasoning.
