The Saint Lucia Blood Bank, a private charity partly supported by government grants, is located on the Caribbean Island of Saint Lucia. The blood bank just finished its operations for September, which was a very busy month because a powerful hurricane caused many injuries on neighboring islands. The hurricane largely bypassed Saint Lucia, but residents of Saint Lucia willingly donated their blood to help people on other islands. As a consequence, the blood bank collected over $20\%$ more blood than originally planned for the month.

A report prepared by a government official comparing actual costs to budgeted costs for the blood bank appears below. Continued support from the government depends on the blood bank's ability to demonstrate control over its costs.
