Hello there!

A) What percent of adults drink only coffee?

Percent of only coffee = 55 - (15 - 5) - (25 - 5) - 5
                                = 55 - 10 - 20 - 5
                                = 20%
Thus, 20% of the adults drink coffee

B) What percent of adults drink only soda?

Percentage of only soda = 45 - (25 - 5) - 5
                                    = 45 - 20 - 5
                                    = 25 - 5
                                    = 20%
Thus, 20% of adults drink only soda

C) What percentage of adults drink none of the beverage types?

Percentage of the beverage types = 100 - 20 - 20 - 5 - 10 - 20 - 5
                                                 = 20%
Thus, 20% percentage of adults drink none of the beverage types.
