Final answer:
Option C). Meg gave 7 apples to Chip.
Step-by-step explanation:
To find out how many apples Meg gave to Chip, we need to use algebraic expression. Let's assume the number of apples Meg gave to Chip is x. According to the question, Meg picked 11 apples and gave some to Chip, then picked 6 more apples. So, the total number of apples Meg had is 11 - x + 6 = 10. By solving this equation, we can find the value of x:
11 - x + 6 = 10
-x + 17 = 10
-x = 10 - 17
-x = -7
x = 7
Therefore, Meg gave 7 apples to Chip. So, the answer is 7 apples (C).
