Question 831342
B + L + D = total amount spent
PD (per diem) = $87
.
10 + 22 + 35 = 67
If you budgeted 87, you don't have a loss.  You have an excess of $20
.
PD-(B+L+D) = profit/loss
.
If, however, you spent 65 on dinner, then you would have 97 total.
87-97 is -10, which is generally written in accounting as <10>.
