angelo and jimmy went shopping. angelo had a. dollars in his wallet. he spent 1/3 of that money on new jeans. jimmy had j. dollars in his wallet. he spent 1/2 of that money on a new jacket. jimmy had more money left than angelo. which expression shows the difference between the amounts of money, in dollars, that each boy had left.

Okay, so Angelo had a dollars and spent 1/3 of that. So he spent 1/3a

Then, the amount he has left can be denoted as: (a - 1/3a)

Jimmy had j dollars and spent 1/2 of it:

So the amount he has left can be denoted as (j - 1/2j)

Since jimmy had more money left, you would subtract the amount angelo has from the amount that jimmy has left.

So: (j - 1/2j) - (a - 1/3a).
