Question: 202

4. A pitcher of lemonade is created using 5 cups of lemon juice, which cost 85 cents per cup, and 7 cups of sugar water, which cost 25 cents per cup. What is the cost, per cup, of the resulting lemonade?

A. $0.30
B. $0.50
C. $0.80
D. $4.25
E. $6.00

Correct Answer: B

Explanation:

B. If the lemon juice costs 85 cents per cup and you're using 5 cups, you're spending $0.85 × 5 = $4.25 on lemon juice. If the sugar water costs 25 cents per cup and you're using 7 cups of sugar water, you're spending $0.25 × 7 = $1.75 on sugar water. That makes 12 cups of liquid, costing $4.25 + $1.75 = $6.00. To determine how much one cup of lemonade costs, divide $6.00 by 12 cups, getting $0.50 per cup, Choice (B).
