You make 7 cups of punch by mixing 4 cups of cranberry juice with 3 of apple juice. how many cranberry juice and how much apple juice do you need to make four times the original recipe

Based om what we know, we can write an equation

4 cups cranberry juice +3 cups apple juice = 7 cups punch

We want to know how many cups of each juice does it take to make 4 times the initial recipe.

Four times the original recipe that makes 7 cups of punch can be written as
4 * 7 which =28 cups of punch

There was 4 cups of cranberry juice in 7 cups of punch, and now there is 28 cups, which
4 times more.

So we multiply 4 cups of cranberry juice by 4 to get 16 cups of cranberry juice.

We do the same for the 3 cups apple juice. We multiply it by 4 to get 12 cups of apple juice.

So we need 16 cups of cranberry juice and 12 cups of apple juice.

Check our answer by adding the two juice together 16+12 = 28, it is indeed our amount of punch which is 7 *4
