Apex Autos charged $9564.90 for the old car Apex Autos made a total profit of $4795

#### Explanation:

We can work this step by step, first, we want to figure out how much profit was gained from the "new car"

Set up an equation where $x$ is the profit from the "new car"
$21,930.00*.14=x x=$3070.20

In my opinion, the fact that the customer paid the price minus the amount of money given was extra information, all we need to know was that Apex Autos bought the "old car" for $7840.00 Now we want to find the profit from the old car, and the new cost after the mark up of the old car $7840.00*.22=$1724.80 giving us the profit of the old car Now we find how much the new old car sold for $7840.00+$1724.80=$9564.90

To find the amount of profit, we can just add the profit of both cars
$1724.80+$3070.20=\$4795
