Question

The price of a pair of jeans was $60 after a 50% markup. What was the price of the jeans before the markup?

Answer 1

$40

Explanation:

Let C be the cost

150% of C = 60

150/100 × C = 60

C = 60 × 100/150

C = 40

Answer 2

40

Explanation:

We have an original price p

We mark them up by 50%

p + p*50%

Changing to decimal form

p+.50p = 1.5p

The new price is 60 dollars

1.5p = 60

Divide each side by 1.5

1.5p/1.5 = 60/1.5

p =40

The original price is 40
