Question

Carol buys last year's best-selling novel, in hardcover, for $25.50. This is with a 15% discount from the original price. What was the original price of the novel?

Answer 1

Answer:

$30.00

Step-by-step explanation:

$25.50 = y(1 - 0.15)

$25.50 = y(0.85)

($25.50) / (0.85) = y

y = $30

Answer 2

Answer:

$30

Step-by-step explanation:

let x = the original price

x - .15x = 25.50  

The original price - .15 of the original price is 25.25

.85x = 25.25  Divide both sides by .85

x = 30

Check:

30 - .15(30) = 25.25

30 - 4.50 = 25.25

25.25 = 25.25
