Answer:

60

Step-by-step 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

Answer: $ 60

Step-by-step explanation:

42 = x (1 - .3)

42 = .7 x

42/.7 = x

X = 60
