The manager of the main laboratory facility at CapitalHealth Center is interested in being able to predict the overhead costs

each month for the lab. The manager believes that total overhead varies with the number of lab tests performed but that some

costs remain the same each month regardless of the number of lab tests performed. The lab manager collected the following

data for the first seven months of the year.

Use the high$-$low method to determine the laboratory's cost equation for total laboratory overhead. Use your results to predict

total laboratory overhead if $2,900$ lab tests are performed next month.
