39.50-23.76-2.57-1.49=11.68
take the sales and subtract the expenses
To solve this, first we calculate all the total cost of
the items that is:
total cost = $14.96 + $19.87 + $5.37
total cost = $40.20
So we see that the actual cost is similar with the
estimate so his calculation is reasonable.
I think it’s 1/3 hope it helps
