Since she sold 6 bags of chips, you have to multiply that amount with the price to see the total for that item. Which is 6 x .50=3.
For apple's its 14 x .20=2.80.
And for Juice boxes its 3 x .75=2.25
You then add all of these numbers which gives you the total of 8.05. You now have to subtract that number from 12.05 to get the remaining price for sandwiches since it was not listed.
