Answer:
40p - 10 = 310
$8
Step-by-step explanation:
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.
Which equation can you use to find p, the original price of each Bright Streak paint set?
Tanvi purchases 40 Bright Streak paint sets. Each paint set costs p dollars. Tanvi uses a $10 coupon and pays $310 in all. This equation represents the situation.
40p
−
10
=
310
cost of all the paint sets
discount applied from coupon
total amount paid
The equation 40p–10=310 can be used to find the original price of each Bright Streak paint set. Solve the equation for p.
40p–10
= 310
40p
= 320 Add 10 to both sides
p
= 8 Divide both sides by 40
The original price of each Bright Streak paint set was $8.
