To determine how many \$7 books Stacey can buy with her remaining money, follow these steps:

1. **Calculate the Remaining Money:**
   
   - **Total Money Stacey Has:** \$50
   - **Cost of the First Book:** \$18

$$
   \text{Remaining Money} = \text{Total Money} - \text{Cost of First Book} = \$50 - \$18 = \$32
   $$

2. **Determine the Number of \$7 Books She Can Afford:**
   
   - **Cost of Each Additional Book:** \$7
   - **Remaining Money:** \$32

$$
   \text{Number of } \$7 \text{ Books} = \frac{\text{Remaining Money}}{\text{Cost per Book}} = \frac{\$32}{\$7} \approx 4.57
   $$

Since Stacey can't purchase a fraction of a book, she can buy **4** \$7 books.

3. **Verify the Total Expenditure:**
   
   - **Cost of 4 \$7 Books:** $$4 \times \$7 = \$28$$
   - **Total Spent:** \$18 (first book) + \$28 (additional books) = \$46
   - **Money Left:** \$50 - \$46 = \$4

Stacey will have \$4 remaining after these purchases.

**Conclusion:** Stacey can buy **4** additional \$7 books with her remaining \$32.
Stacey can buy 4 \$7 books with her remaining \$32.

Stacey has \( \$ 50 \) to buy books. She buys one book for \( \$ 18 \). The other books she wants each cost \( \$ 7 \). How many \( \$ 7 \) books can she buy with the money left over?
