Question

Sandra mixes 1/4 cup of raisins with 3 1/2 cups of apples for a summer salad. How many cups of apples does she need if she wants 30 cups of the salad altogether? We know 28/30 cups of apples are needed for 1 cup of salad. How many cups of apples will be needed for 30 cups of salad? a. 26 2/3 cups of apples.

b. 25 cups of apples.
c. 28 1/2 cups of apples.
d. 30 1/4 cups of apples.

Answer 1

Sandra needs 28 cups of apples to make 30 cups of salad, using the proportion of 28/30 cups of apples required per cup of salad. The correct answer is option c.

Step-by-step explanation:

To find out how many cups of apples are needed for 30 cups of salad, we can use the information given that 28/30 cups of apples are needed for 1 cup of salad. Using a simple proportion, we multiply the fraction of apples needed per cup of salad by the total amount of salad desired.

Step 1: Set up the proportion using the fraction for apples needed per cup of salad (28/30) and multiply by the total salad cups (30). Step 2: Calculate: (28/30) x 30 = 28 x (30/30) = 28 x 1 = 28 cups of apples. Therefore, for 30 cups of salad, Sandra needs 28 cups of apples.
