To find the percent increase in sales, first calculate the difference between the new sales and the old sales:

$5,400,000 - $4,800,000 = $600,000

Next, divide the difference by the old sales and multiply by 100 to get the percent increase:

$600,000 / $4,800,000 * 100 = 12.5%

Therefore, the percent increase in sales is 12.5%.
