You didnĀ“t post the complete information of the exercise, I searched the exercise online and tried to ask the most useful question.
Step-by-step explanation:
a) current margin = Sale price - Cost
= $42 - $28 = $14 per unit
(b) Selling price if margin is 49%
= Cost / (1-0.49)
= 28 / 0.51
= $55
Profit = 55*49% = 227
(c) Price to consumer = Selling price / (1-0.1)
= 55/ 0.9
= $61.1
(d) Price to Consumer = Selling price from Chengg + Margin
= 61 + 10 = $71
