Answer:
80 cups of water will be needed.
Step-by-step explanation:
Let the equation that represents the amount of lemonade mix (y) and the cups of water needed (x) for second recipe is,
y = mx
Here, m = rate of change (amount of water required for a cup of lemonade mix)
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m = [tex]\frac{65-50}{13-10}[/tex] = 5
Therefore, equation will be,
y = 5x
If x = 16,
y = 5×(16)
y = 80 cups
Therefore, 80 cups of water will be needed to prepare 16 cups of lemonade mix.
