Using the high low method, which of the following is the correct cost equation using the following information:

Month Total Operating Expenses $($total cost y axis$)$ Number of Oil Changes $($volume x axis$)$

April $32,5002,700$

May $37,0003,600$

June $33,7002,900$

Remember, the high low method has $3$ steps! Make sure you're selecting the highest and lowest volume!

Question $1$ options:

Y $=$ $$5($x$)+$ $$19,000$

Y $=$ $$19,000($x$)+$ $$5$

Y $=$ $$7\mathrm{.}50($x$)+12,400$

Y $=12,400($x$)+$ $$7\mathrm{.}50$
