Answer: the regular price for a bag of mulch is $3.5
Step-by-step explanation:
Let x represent the regular price for a bag of mulch.
Catherine purchases 8 bags of cyprus mulch. It means that the original cost for 8 bags of cyprus mulch is 8x
She has a coupon for $0.75 off each bag of mulch. It means that the value if the coupon for 8 bags of mulch is
8 × 0.75 = $6
After applying her coupon towards the purchase, the total cost of the mulch is $22. It means that
8x - 6 = 22
8x = 22 + 6 = 28
x = 28/8
x = 3.5
