"The difference of" means subtraction

"and twice that number" means 2N
So the statement is the subtraction of 5N and 2N

5N - 2N

1. Dalia makes a cranberry apple punch that contains 20%, percent real juice by mixing x gallons of a cranberry drink with y gal
Vladimir79 [104]

Answer:

The required equations which represents the relationship between x and y is 0.2(x+y)=0.4x+0.1y.

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: \frac{20}{100}(x+y)

The cranberry drink contains 40 percent real juice and the apple drink contains 10 percent real juice.

This can be written as: \frac{40}{100}x+\frac{10}{100}y

Now both the equation are equal.

\frac{20}{100}(x+y)=\frac{40}{100}x+\frac{10}{100}y

0.2(x+y)=0.4x+0.1y

Hence, the required equations which represents the relationship between x and y is 0.2(x+y)=0.4x+0.1y.
