The rice will cost $17.6 for serving 40 people
<h3><u>Solution:</u></h3>We need to determine the cost of serving 40 people with rice
Arborio rice is purchased in 2-pound boxes for $1.99
The price of 1 pound box will be
1 Pound (lb) is equal to 16 ounces (oz)
Therefore, the price of 16 ounces is $0.995
A cup of raw Arborio rice weighs 7 ounces and it serve 1 people
Therefore rice will cost $17.6 for serving 40 people
To solve this problem you have to set up a proportion. To form one side of the proportion you use "is over of" meaning what number represented by is, in this case 18, is placed over the number represented by of, 3000. 
Since you are finding the percent of something, youre x value is placed above "100" because percent values are most commonly out of 100%. 
So now your proportion will look like To solve the proportion you cross multiply and divide. So you multiply 100 and 18 since they are crossed from each other, then divide 1800 by 3000. The answer is .6. 18 is .6% of 3000.
So now your proportion will look like
