\begin{tabular}{l} Question 16 \\ \hline A clothing store charges \( \$ 25 \) for 4 t-shirts. A student says that the \\ unit price is \( \$ 0.16 \) per t-shirt. What is the error? What is the correct \\ unit price? \end{tabular}

To find the unit price of the t-shirts, we need to divide the total cost by the number of t-shirts. The total cost for 4 t-shirts is \( \$25 \). To find the unit price, we calculate: \[ \text{Unit Price} = \frac{\text{Total Cost}}{\text{Number of T-shirts}} = \frac{25}{4} \] Calculating this gives: \[ \frac{25}{4} = 6.25 \] So, the correct unit price is \( \$6.25 \) per t-shirt. The student's claim that the unit price is \( \$0.16 \) per t-shirt is incorrect. The error likely arises from a miscalculation or misunderstanding of how to divide the total cost by the number of items.
