The blood bank has just finished its operations for September, which was a very busy month due to a powerful hurricane that hit neighboring islands causing many injuries. 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 and processed over $20\%$ more blood than had been 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.
