Answer:
$386.75
Step-by-step explanation:
First we must find the price of the camera after the man sold it, with the 10% loss.
To do this we find 10% of 414, which is 41.4 . Meaning the camera was originally bought from the dealer for $455.40, as we have to add the 10% back onto the price.
Now we find 15% of 455 and subtract it, with 15% being 68.25, the original cost was $386.75. My guy was seriously ripped off :(.
<h2>Orignal price: $386.75</h2>
