Answer :
With 30% profit, the selling price of a microwave is $273. If the profit is decreased to 10%, its selling price will be $231
The relation among profit, selling price, and cost price is given by:
Profit = selling price - cost price
Percentage of profit on the cost = profit / cost price x 100%
Data from the problem:
Percentage of profit on the cost = 30%
selling price = $273
Let:
c = the cost price
p = profit
Hence,
30% = p / c
p = 30% c = 0.3 c
Meanwhile:
p = selling price - c
p = 273 - c
0.3 c = 273 - c
1.3 c = 273
c = 210
Scenario 2: if the profit is 10% on the cost, then
p = 10% c = 10% x 210 = 21
Therefore,
selling price = p + c = 21 + 210 = 231
