Q. Tanvi teaches art lessons at a day camp and needs to get supplies. She purchases Bright Streak paint sets from the Color Splash art store. She uses a coupon she received in the mail for off her purchase. Tanvi spends in all. Which equation can you use to find , the original price of each Bright Streak paint set? What was the original price of each Bright Streak paint set?
- Set up the equation: Let's set up the equation. Tanvi's total spending after the discount is \$\(310\). If she bought \(40\) paint sets and used a \$\(10\) coupon, the equation to find the original price per set, \(p\), is: \(40p - 10 = 310\).
- Solve for \(p\): Solve for \(p\). First, add \(10\) to both sides to isolate the term with \(p\): \(40p - 10 + 10 = 310 + 10\), which simplifies to \(40p = 320\).
- Divide to find \(p\): Next, divide both sides by \(40\) to find \(p\): \(p = \frac{320}{40}\), which equals \(8\).
