Understand Problem Context: Understand the context of the problem.Ray is buying ginger roots with a price of G. He has a coupon that gives him 10% off. The expression 0.9G represents the price he pays after the discount.
Determine Meaning of 0.9: Determine what 0.9 represents in the expression 0.9G.Since the coupon gives a 10% discount, this means Ray is paying 100%−10% of the original price. In decimal form, 100% is 1 and 10% is 0.1. Therefore, Ray is paying 1−0.1, which equals 0.9 of the original price.
