Question

A new car has a sticker price of $\$22,450,$ while the invoice price paid was $\$19,450$. What is the dealer markup?

Answer 1

The formula for the selling price of an atom, a new car in this case, is:
$s=c+m$
Where:
$s$ is the selling price or sticker price $-\$22,450$ in this problem
$c$ is the cost or invoice price paid $-\$19,450$ in this problem
$m$ is the markup, what needs to be solved for in this problem.

Substituting the information from the problem and solving for m gives:
$\$22,450=\$19450+m$
$\$22,450-\$19450=\$19450+m-\$19450$
$\$22,450-\$19450=\$19,450-\$19,450+m$
$\$3,000=\$0+m$
$\$3,000=m$
