Elise does not like sorbet, so she omits that ingredient and adds 5 percent of each of the other ingredients. How many cups of punch will she have if she uses 6 cups of orange Juice

This problems is bases on this table of ingredients (which you omitted, but is mandatory):

Ingredient %

Ginger Ale 40%

Orange Juice 25%

Pineapple juice 20%

Sorbet 15%

You can verify that the four ingredients sum up 100%

Now, Elise omits the sorbet and substitute it for 5% each of the other.

Then the new formula is

Ginger Ale: 45%

Orange juice 30%

Pineapple juice 25%

Which, of course, sums up 100%.

Now use the proportion of orange juice to the total to find how many cups of punch she will have if she uses 6 cups of orange juice:

25 cups of Pineapple juice / 100 cups of punch = 6 cups of pineapple juice / x cups of punch

And solve for x, to obtain; x = 6 cups of pineapple juice * [100 cups of punch / 25 cups of pineapple juice]

x = 24 cups of punch

Answer: 24 cups of punch
