To solve the problem, we need to determine how many eight-packs of iced tea the vending machine can hold, given that it holds 143 bottles of iced tea. 1. **Understanding the problem:** - The vending machine holds a total of 143 bottles. - Each eight-pack contains 8 bottles. 2. **Calculating the number of eight-packs:** To find out how many eight-packs can fit into the vending machine, we divide the total number of bottles by the number of bottles in each eight-pack. \[ \text{Number of eight-packs} = \frac{\text{Total bottles}}{\text{Bottles per eight-pack}} = \frac{143}{8} \] 3. **Performing the calculation:** Let's calculate this division. \[ \frac{143}{8} = 17.875 \] Since we cannot have a fraction of an eight-pack, we take the whole number part of the result, which is 17. 4. **Conclusion:** The vending machine can hold 17 eight-packs of iced tea. Thus, the answer is **A. 17**.
