To find out how much Maria will save per ounce, we need to subtract the cost per ounce of the less expensive selection from the cost per ounce of the more expensive selection.
For the 12-ounce bag:
Cost per ounce = $2.40 ÷ 12 = $0.20/ounce
For the 60-ounce container:
Cost per ounce = $18.00 ÷ 60 = $0.30/ounce
Maria will save $0.30 - $0.20 = $0.10 per ounce by making the less expensive selection.

To find out how many napkins should be ordered for 15 guests, we can set up a proportion.
We know that 400 napkins is enough for 8 guests.
Let's call the unknown number of napkins needed for 15 guests as "x".
So we can set up the proportion:
400 napkins / 8 guests = x napkins / 15 guests
Cross-multiplying, we get:
8 * x = 400 * 15
8x = 6000
x = 6000 / 8
x = 750
Therefore, 750 napkins should be ordered for 15 guests.

Since the chef uses 2 cups of broth for every 1/3 cup of rice, we can set up a proportion to find out how many cups of broth are needed for 6 cups of rice.
2 cups of broth / 1/3 cup of rice = x cups of broth / 6 cups of rice
Cross-multiplying, we get:
(2 cups of broth) * (6 cups of rice) = (1/3 cup of rice) * (x cups of broth)
12 cups of broth = 2 cups of rice * x
Dividing both sides by 2 cups of rice, we find:
x = 12 cups of broth / 2 cups of rice
x = 6 cups of broth
Therefore, 6 cups of broth are needed for 6 cups of rice.
