i. Amount paid by Edwin on 22 September 2023:
List price = RM8,400
Trade discount = 10%
Amount after trade discount = RM8,400 - (10% of RM8,400) = RM8,400 - RM840 = RM7,560
Amount to be paid = Amount after trade discount - (Cash discount of 4% of Amount after trade discount)
= RM7,560 - (4% of RM7,560)
= RM7,560 - RM302.40
= RM7,257.60
Amount paid by Edwin on 22 September 2023 = RM7,257.60
ii. Selling price:
Gross profit = 25% of selling price
Operating expenses = 4% of selling price
Gross profit + Operating expenses = 25% of selling price + 4% of selling price
29% of selling price = Gross profit + Operating expenses
Selling price = (Gross profit + Operating expenses) / 29%
Selling price = (25% + 4%) / 29% = 29% / 29% = 100%
Selling price = RM7,560
iii. Breakeven price:
Breakeven price = Cost price / (1 - Gross profit percentage)
Breakeven price = RM7,560 / (1 - 25%)
Breakeven price = RM7,560 / 0.75
Breakeven price = RM10,080
iv. Maximum markdown percent that could be given without incurring any loss:
Let x be the markdown percent
Selling price after x% markdown = Cost price
(100% - x%) of Selling price = Cost price
(100% - x%) of RM7,560 = RM7,560
0.01x * RM7,560 = RM7,560
x = 1
Therefore, the maximum markdown percent that could be given without incurring any loss is 1%.
v. Net profit obtained by Edwin:
Net profit = Gross profit - Operating expenses
Net profit = 25% - 4%
Net profit = 21%
Net profit = 21% of RM7,560 = RM1,585.60
Therefore, the net profit obtained by Edwin is RM1,585.60.
