The problem asks how much Terry spent on socks after visiting a store 7 times, with each visit involving the purchase of 2 packages of socks costing $9 each.

We can calculate this step by step:

- Each visit, Terry buys **2 packages of socks** at **$9** each. Therefore, in each visit, he spends:
  \[
  2 \times 9 = 18 \, \text{dollars per visit}
  \]
- Since Terry visited the store **7 times**, the total amount he spent is:
  \[
  7 \times 18 = 126 \, \text{dollars}
  \]
Thus, the correct expression representing this situation is:
\[
7 \times (9 + 9)
\]
since $9 + 9$ represents the total cost for two packages per visit, and he visited 7 times.

This corresponds to option **C: $ 7(9 + 9) $**.

Would you like further details on the calculations or have any questions?

Here are five related questions to deepen your understanding:
1. How would the expression change if each package of socks cost $10?
2. If Terry bought 3 packages per visit, how would you modify the expression?
3. How can you represent the total amount using an addition-based expression rather than multiplication?
4. If Terry had only visited the store 5 times, how would you adjust the expression?
5. What would the expression be if Terry received a 10% discount on each package?

**Tip:** Always break down word problems step by step, identifying how many units of an item are bought and the cost per unit.

Each time Terry visits the discount store, he buys 2 packages of socks for $9 each. Terry has gone to the discount store 7 times in the last 6 months. Which expression shows how much Terry spent on socks?
