Jay King, owner of a local Bed and Bath Store knows that his customers will only pay at most, $299 for a blow up bed. Assuming Jay wants a 40% markup on selling price, the most he could pay the manufacturer for the blow up bed is

If you would like to know the price Jay can pay the manufacturer for the blow up bed, you can calculate this using the following steps:

100% + 40% = 140%

140% of x is $299

140% * x = 299

140/100 * x = 299 / * 100/140

x = 299 * 100 / 140

x = $213.6

40% of $213.6 = 40% * 213.6 = 40/100 * 213.6 = 85.44

$213.6 + $85.44 = $299

The correct result would be $213.6.
