Answer:
12 cups of sugar
Step-by-step explanation:
The recipe uses 3 cups of sugar for every 8 cups of flour.
The diagram that models the ratio is the upper one with 3 pink squares of sugar and 8 green squares of flour.
If she uses 32 cups of flour, she is making 4 times the recipe since 32 = 4 × 8.
Then she also needs 4 times the amount of sugar.
4 × 3 = 12
Answer: 12 cups of sugar
