Amovie theater sells 5 different beverages in small, medium, or large cups. if the theater adds one more beverage choice, how does the number of possible combinations change? a- it increases by 1.b- it increases by 3.c- it increases by 5.d- it increases by 15.

B- It increases by 3.

To find the number of possible combinations, multiply the number of different beverages by the number of sizes of cups.

5 × 3 = 15

The number of possible combinations with 5 different beverage choices is 15. If the theater adds one more beverage choice, there will be 6 different beverage choices.

6 × 3 = 18

We can find how the number of possible combinations changes by subtracting the number of different combinations for each number of different beverages.

18 - 15 = 3

B- It increases by 3.
