Question

Janine found a perfect sundress for 30% off. The original price, before tax, was $60. What was the sale price of the dress before tax?

Answer 1

Multiply 60 by 0.30, the decimal form of 30%

Answer 2

price - 30%×price = price×(1 -0.30) = 0.70×price
  = 0.70×$60 = $42

The sale price of the dress before tax was $42.
