Using High$-$Low to Calculate Predicted Total Varlable Cost and Total Cost for Budgeted Output

Pizza Vesuvio makes specialty pizzas, Data for the past $8$ months were collected:

$\backslash$table$[[$Month$,\backslash$table$[[$Labor$],[$Cost$]],\backslash$table$[[$Employee$],[$Hours$]]],[$January$,$$$7,000,330],[$February$,8,140,520],[$March$,9,899,630],[$April$,9,787,580],[$May$,8,490,450],[$June$,7,450,320],[$July$,9,490,540],[$August$,7,531,280]]$

Assume that this information was used to construct the following formula for monthly labor cost.
