Question

A total of 65 pounds of iceberg lettuce heads are purchased for use in a banquet of 120 people. If 6 ounces of cleaned chopped lettuce is required for each person and the yield percentage is 80%, how much chopped lettuce will be left over?

Answer 1

20 pounds

Explanation:

Convert pounds into ounces.

1 pound = 16 ounces

65 pounds = 65 * 16 = 1040 ounces.

Each person required 6 ounces of chopped lettuce.

Chopped lettuce required for 120 people = 120 *6

= 720 ounces.

Left over chopped lettuce = 1040 - 720

= 320 ounces

When we convert ounces to pounds, we get

320/16 = 20 pounds.

20 pounds of iceberg lettuce left over.

Thank you.

Answer 2

7 pounds

Explanation:

1. You must convert 6 ounces to pounds:

`(6)(0.0625)=0.375pounds`

2. Now you must multiply this by 120 persons:

`(0.375)(120)=45pounds`

3. Now, you have to multiply 65 ounces by 80% and substract the pounds obtained above:

`(65)(0.80)-45=7pounds`
