Alma owns a lawn care business and recently performed some research on the size of $50$ lawns that she takes care of.
Alma recalls that she is expected to take care of a total of $21$ acres of lawn for every $6$ customers that she serves. She also knows that she has $4$ customers with $1$ acre of lawn, $6$ customers with $2$ acres of lawn, and $9$ customers with $5$ acres of lawn.
Unfortunately, Alma can’t find the information on the number of customers that have $3$ or $4$ acre lawns.
**Find the $2$ missing numbers from the data table below.**
