The required equations which represents the relationship between x and y is
.
Step-by-step explanation:
Consider the provided information.
Dalia makes a cranberry apple punch that contains 20%, percent real juice by mixing x gallons of a cranberry drink with y gallons of an apple drink.
This can be written as:
