How many ounces of Halloween candy does Jack have left?

Step-by-step explanation:

Amount of halloween candy bought by Jack = 5pounds

Amount he gave trick = 3pounds

Amount jack ate = 10ounces

Before we can determine the amount of halloween candy that Jack has left, we need to convert the pounds to ounces in order to make the units consistent.

given 1pound = 16ounces

5pounds = 16* 5 ounces

5pounds = 80ounces

Also;

3pounds = 16*3 ounces

3pounds = 48ounces

Total amount of halloween used up by Jack = 48ounces + 10ounces

= 58ounces

Amount of ounces of candy left = Total amount of candy bought -amount used up

Amount of ounces of candy left = 80ounces - 58ounces

Amount of ounces of candy left = 22ounces
