Question

Frank had b bottles of water before his friends came over. His friends drank 8 bottles of water. After his friends left, Frank went to the store and bought 18 bottles of water. Which expression shows how many bottles of water Frank has currently

Answer 1

The expression that shows how many bottles of water Frank currently has is b + 10.

Step-by-step explanation:

To determine how many bottles of water Frank currently has, we start with the number of bottles he had before his friends came over, which is represented by the variable b. Then, we subtract the number of bottles his friends drank, which is 8. Next, we add the number of bottles Frank bought at the store, which is 18. This can be expressed using the following expression:

b - 8 + 18

If we simplify this expression, we get:

b + 10

Therefore, the expression that shows how many bottles of water Frank currently has is b + 10.
