If the seller sells his calculator for 97 dollars he will be on 15% loss . What is the percentage he wins if he sells it for 143 dollars ?

Question

Hi ! 

The answer is 25% i just cannot get there .

Answer 1

If c is the cost of the calculator.

$97 is 85% of the purchase cost

 

.85c = 97

c = 97/.85

c = $114.12

He paid $114.12 for the calculator

 

143 = x% of 114.12

143 = (x/100)(114.12)

x = 143(100)/114.12

x = 125.3% of the purchase cost

 

If he sell if tor $143 he will make a 25.3% profit
