Can someone explain to me why only the $800 is included in the charitable contribution and not the $350 billing rate per hour as well? please help and thanks in advance!

During the current year she spends a total of 200 hours in this volunteer work. Her regular billing rate is $350 per hour. In addition, she spends a total of $800 in out-of-pocket costs in providing these services. She receives no compensation and is not reimbursed for her out-of-pocket costs. Requirement What is Donna's charitable contribution for the year because of these activities? Donna's charitable contribution for the year is $ 800.
