Question 13.
Amy has 30 grams of flour. She puts 4 grams of flour in each pot of chowder that she makes. She puts 5 grams of flour in each pot of potato soup that she makes. She makes 4 pots of chowder. Does Amy have enough flour left over to make 3 pots of potato soup?
______

Answer: No

Explanation:
Mass of flour Amy has= 30grams
Mass of flour in each pot of chowder= 4grams
Mass of flour in each pot of potato soup= 5grams
According to the problem,
Amy makes 4 pots of chowder.
Mass of flour used to make 4 pots of chowder= 4×4= 16grams
Leftover mass of flour=30-16=14 grams
Mass of flour used to make 3 pots of potato soup=5×3=15 grams
