Students use a shopping list to purchase clothing to donate to needy children on a shopping trip.

1. Students have a gift card allowance of $150.00 to spend.
2. Students purchase as much as they can for one girl and one boy without going over the $150.00 budget.
3. Students enter their chosen clothing items and costs in a spreadsheet.
4. Students use the sum function to calculate total expenses from a column of values (clothing expenses).
5. Students use a simple formula to calculate money left over (allowance - total clothing expenses).
