Answer:
- 10 cups
- c. 1 : 5
Step-by-step explanation:
1. The basic recipe for Kool Aid makes 2 quarts. The desired amount is 20 quarts (2 multiplied by 10). The basic recipe uses 1 cup of sugar, so the desired amount of Kool Aid will use 1 cup multiplied by 10.
10 cups of sugar are needed

2. The problem tells us there are 8 parts pretzels and 40 total parts, so the ratio is ...
pretzels : total = 8 : 40
8 is a factor of both these numbers, so we can reduce this to the "basic ratio" by dividing both numbers by 8:
8 : 40 = 1 : 5
The basic ratio is 1 : 5.
