(5 points) part b: how many liters of cranberry juice are present in the punch? show your work.

There are 8 liters of cranberry juice in the punch

Step-by-step explanation:

Part A

We know that of the punch, 80% is cranberry juice.

Let's call Z the amount of cranberry juice and Y is the amount of ginger ale.

Let's call X the amount of Ponche

The amount of punch is equal to the amount of cranberry juice plus the amount of ginger ale

(i)

Then we know that:

 (ii)

We also know that:

liters (iii)

Part B.

Now we can solve the equation:

Replace (ii) and (iii) in (i)

X = 10 liters.

Now we substitute X = 10 in equation (ii) and find the amount of Cranberry juice.

Z = 8 liters.

There are 8 liters of cranberry juice in the punch

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
