For $2023,$ what is Ford$$s Sales volume estimate to break even? Assume:

The operating expense in $2023$ will have grown at a rate $($compared to $2022)$ that is the average of the annual growth rates of each year from $2020$ to $2022.$

The ratio of COGS $($or Cost of Sales$)$ to total sales $($revenue$)$ in $2023$ will be the average of the ratios in the three years of $2020$ to $2022.$
