Be careful that you do not calculate $28\%$ of $\$2200\text{.}$ That might be what a student would do who doesn’t thoroughly read the question. If you have ever trained yourself to quickly find numbers in word problems and substitute them into formulas, you must unlearn this. The issue is that $\$2200$ is not the dealership’s sales profit, and if you mistakenly multiply $0.28\cdot2200=616\text{,}$ then $\$616$ makes no sense as an answer to this question. How could Alexis bring in only $\$616$ of sales profit, and be rewarded with $\$2200$ in commission? We can translate the problem into “$\$2200$ is $28\%$ of what?” Letting $x$ be the sales profit for the dealership (in dollars), we can write and solve the equation: $$\begin{aligned} \pinover{2200}{\$2200}\amp\pinover{=}{is}\pinover{0.28}{28\%}\pinover{\cdot}{of}\pinover{x}{what}\\ \divideunder{2200}{0.28}\amp=\divideunder{0.28x}{0.28}\\ 7857.14\amp\approx x\\ x\amp\approx7857.14 \end{aligned}$$ To earn $\$2200$ in commission, Alexis needs to bring in approximately $\$7857.14$ of sales profit for the dealership.
