Question

An electronics store is selling mp3 players for 30% off. A customer purchases an mp3 player for $42. What was the price of that mp3 player before the reduction?

Answer 1

Answer: $ 60

Explanation:

42 = x (1 - .3)

42 = .7 x

42/.7 = x

X = 60

Answer 2

60

Explanation:

If the price is 30% off, you pay 70% of the price

Let x be the original price

.70x = sale price

.70x = 42

Divide each side by .7

.70x/.7 = 42/.7

x =60

The original price is 60
