Question

ray is buying some ginger roots to brew some fresh ginger ale. the price of the ginger roots is g, and ray has a coupon for 10% off. the expression 0.9g represents the price ray pays for the ginger roots after using the coupon. what does 0.9 represent in this context? choose 1 answer: a the amount of the discount from the coupon b the percent, as a decimal, of the discount from the coupon c the percent, as a decimal, of the original price that ray pays d the amount ray pays after using the coupon

Explanation:

Step1: Analyze Option A

The discount amount would be \( 0.1G \) (since 10% of \( G \) is \( 0.1G \)), not \( 0.9 \). So A is incorrect.

Step2: Analyze Option B

The discount percent as a decimal is \( 0.1 \) (10% = 0.1), not \( 0.9 \). So B is incorrect.

Step3: Analyze Option C

If the original price is \( G \) and there's a 10% discount, Ray pays \( 100\% - 10\% = 90\% \) of the original price. 90% as a decimal is \( 0.9 \), so \( 0.9G \) means he pays 0.9 (or 90%) of the original price \( G \). This matches.

Step4: Analyze Option D

The amount Ray pays is \( 0.9G \), not \( 0.9 \) (since \( 0.9 \) is a multiplier, and the amount depends on \( G \)). So D is incorrect.

Answer:

C. The percent, as a decimal, of the original price that Ray pays
