Using High$-$Low to Calculate Fixed Cost, Calculate the Variable Rate, and Construct a Cost Function

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

$\backslash$table$[[$Month$,$Labor Cost,Employee Hours$],[$January$,$$$7,000,360],[$February$,8,140,550],[$March$,9,899,630],[$April$,9,787,610],[$May$,8,490,480],[$June$,7,450,350],[$July$,9,490,570],[$August$,7,531,310]]$

Pizza Vesuvio's controller wants to calculate the fixed and variable costs associated with labor used in the restaurant.

In your calculations, round the variable rate per employee hour to the nearest cent.

Required:

Using the high$-$low method, calculate the variable rate.

per employee hour

Using the high$-$low method, calculate the fixed cost of labor.

$

Using the high$-$low method, construct the cost formula for total labor cost.
