What is the cost for one shirt?

Answer 1

To find the unit price (cost per shirt), you can divide the total cost by the quantity for each case. Here's the calculation for each quantity listed:

1. For 6 shirts costing $18: \[ \text{Unit Price} = \frac{\text{Total Cost}}{\text{Quantity}} = \frac{18}{6} = 3 \]

2. For 5 shirts costing $15: \[ \text{Unit Price} = \frac{15}{5} = 3 \]

3. For 4 shirts costing $12: \[ \text{Unit Price} = \frac{12}{4} = 3 \]

4. For 3 shirts costing $9: \[ \text{Unit Price} = \frac{9}{3} = 3 \]

In each case, the cost for one shirt is $3.
