Question 1179486
<br>
Selling at a 5% discount means selling at 95% of the usual price; selling at a 25% discount means selling at 75% of the usual price.  The difference in his earnings between selling at those two prices is $3300.<br>
{{{.95x-.75x=3300}}}
{{{.2x=3300}}}
{{{x=16500}}}<br>
The usual price is $16,500.<br>
His cost price is $2400 less than what he sells it for if he sells at a 5% discount from the usual price:<br>
{{{.95(16500)-2400=15675-2400=13275}}}<br>
or it is $900 more than what he sells it for if he sells it at a 25% discount from the usual price:<br>
{{{.75(16500)+900=12375+900=13275}}}<br>
ANSWER: His cost price was $13,275<br>
