pls help!

The mansger of the main laboratory tacilty at Urbantiesith Center is interested in being able to predict the overhead costs each month for the lab. The manager bolieves 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. (Click the icon to view the data) Use the high-tow method to determine the laboratcor's cost equahon for total laboratory overhead. Use your results to prodict total laboratory overhead 62,700 lab tests are performed next month. Let's begin by determining the formula that is used to calculate the variable cost (sope). Change in cost Now determine the formula that is used to calculate the fixed cost component. Use the high-low method to determine Urtantheath's cperating cost equation. (Round the variable cost to the nearest cent) y=x+ Data table to predict total
