Peter, the pumpkin eater, wanted to make two pies for a party. His
mother, a professional pie maker, had a recipe for him to use.
However, she always made 80 pies at a time. She used:
10 dozen eggs
27 liters of condensed milk
480 tablespoons of sugar
100 teaspoons of cinnamon
140 cups of pumpkin
Peter looked in the cupboard and found:
4 cups of pumpkin
3 eggs
1 1/2 teaspoons of cinnamon
2/3 of a liter of condensed milk
15 tablespoons of sugar
Did Peter have enough ingredients to make two pumpkin pies for the party or did he need to
buy more?
