Answer:

Price of rice per gram = $ 0.006 per gram or 0.6 cents per gram .

Explanation:

Given: David wants to make 10 servings, where each serving has 75 grams of rice.

Total quantity of rice required = 10 x 75 = 750 grams

Overall, David spends 4.50 dollars on rice.

i.e. cost of 750 grams of rice = 4.50 dollars

Price of rice per gram =(cost of 750 grams of rice ) ÷ 750

= (4.50 dollars ) ÷ 750

= $ 0.006 per gram.

Price of rice per gram = $ 0.006 per gram.
