Based on the shipping rate and the price of the t-shirts, it can be concluded Sam ordered a total of 6 t-shirts.
<h3>What equation represents Sam's situation?</h3>
5.99 + x12.50 = 80.99
x represents the number of t-shirts she bough, which is the focus of the equation.
Let's solve it:
- 5.99 + x12.50 = 80.99
- x12.50 = 80.99 - 5.99
- x12.50 = 75
- x = 75 / 12.50
- x = 6
<h3>How many t-shirts did Sam order?</h3>
Sam ordered 6 t-shirts.
