Answer: Option (d) is correct.
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
= 500 × $0.72 each
= $360
Total sale value = $375 + $1,980 + $360
= $2,715
= 72.92%
Proportion of cost for Group 2 = cost × Percentage of sale in Group 2
= $1,500 × 72.92%
= $1,093.8
= $0.1988
= $0.20(approx)
