To find out how many drinks are left in the cooler, we need to subtract the number of drinks each person drank from the total number of drinks in the cooler.
Let's calculate the number of drinks each person drank:
Joey drank 15% of the drinks. So, 15% of 20 is (15/100) * 20 = 3 drinks.
Sandra drank 1/5 of the drinks. So, 1/5 of 20 is (1/5) * 20 = 4 drinks.
Hannah drank 1/4 of the drinks. So, 1/4 of 20 is (1/4) * 20 = 5 drinks.
Tammy drank 30% of the drinks. So, 30% of 20 is (30/100) * 20 = 6 drinks.
Now, let's subtract the number of drinks each person drank from the total number of drinks:
Total drinks in the cooler = 20 - (3 + 4 + 5 + 6) = 20 - 18 = 2 drinks.
Therefore, there are 2 drinks left in the cooler.
The answer is option B.
