Tanvi teaches art lessons at a day camp and needs to get supplies. She purchases 40 Bright Streak paint sets from the Color Splash art store. She uses a coupon she received in the mail for $10 off her purchase. Tanvi spends $310 in all.

Question

Which equation can you use to find p, the original price of each Bright Streak paint set?
What was the original price of each Bright Streak paint set?

Answer 1

Let p be the original price of each Bright Streak paint set.

The equation to find p is:
40p - 10 = 310

To solve this equation for p, we can first add 10 to both sides:
40p = 320

Then divide both sides by 40:
p = 8

Therefore, the original price of each Bright Streak paint set was $8.
