The Red Wolf Society, a nongovernmental not−$-$for−$-$profit organization, receives numerous contributed hours from volunteers during its busy season. Tom, a clerk at the local government utility$\mathrm{â??}$s office, volunteered ten hours per week for eight weeks transferring wolf food from the port to the wolf shelter. His rate of pay at the utility office is $20$\mathrm{20}$per hour, and the prevailing wage rate for laborers is $15per hour.
