Pete wants to mix 4 quarts of 20% orange juice concentrate with some 60% pineapple juice concentrate to get a 50% punch concentrate for a party. How much of the 60% pineapple juice concentrate should be used? please answer ASAP and explain thought process

Answer 1

• 12 quarts

Explanation:

Let the amount of pineapple juice be x quarts, the concentration of juice is as following equation:

• 4*0.2 + x*0.6 = (4 + x)*0.5
• 0.8 + 0.6x = 2 + 0.5x
• 0.6x - 0.5x = 2 - 0.8
• 0.1x = 1.2
• x = 12
