He currently has 40 grams of the spice blend, and he can go buy more if necessary. He wants to make 10 servings, where each serving has 75grams of rice. Overall, David spends 4.50, point, 50 dollars on rice. What is the price of rice per gram?

Answer 1

Answer:

1g rice = 0.6 cents = $0.006

Step-by-step explanation:

See the image for details.

First of all, the spice part of the table doesn't really matter at all.

For the first real step to manipulate the equation, you should multiply the 15 grams of rice by 5 so you get 1 serving:

15 * 5 = 75

Then, you multiply those 75 grams of rice by 10 because there are 10 servings:

75 * 10 = 750

After that, create this equation:

750g rice = $4.50

And, manipulate it:

1g rice = $0.006
