For 5 gallons of punch = craberry juice required is 4 cups

For 1 gallon of punch = cranberry juice required is x cup

By cross multiplying;

x = (1 × 4) / 5

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
