5) Rory sold T-shirts at a festival for $15 each. He paid $100 in materials and fees. Rory's profit after the festival was $350. He wants to know how many shirts he sold,
6) Which quantity is unknown?
6) the number of shirts sold
• Let s equal the number of shirts sold. Which equation represents the situation?
15(8 – 100) = 350
158 = 350
8 - 100 = 350
158 - 100 = 350

We need to find the number of shirts he sold using: 15s - 100 = 350

s = 30

So, Rory sold 30 shirts :)
