Explanation:
Amount paid for candy = $1,500
Items received = 8,500 pieces of candy
Group 1 = 2,500 pieces
Selling price = $0.15 each
sale value = pieces sold × Selling price
= 2,500 × $0.15 each
= $375
Group 2 = 5,500 pieces
Selling price = $0.36 each
sale value = pieces sold × Selling price
= 5,500 × $0.36 each
= $1,980
Group 3 = 500 pieces
Selling price = $0.72 each
sale value = pieces sold × Selling price
