The price of the TV is $4380 after after a 40% discount

The original price=4380/(1-40%)=7300
The money saved for the first discount=7300-4380=2920

further 10% is given

The money saved for the second discount=4380x10%=438

Total amount saved=2920+438=3358

current price = $4380 = original x 60% original = $4380 / 60% = $7300if further 10% discount is given on current price, the new price will be $4380 x 90% = $3942original - new discounted price = $7300 - $3942 = $3358 列式original price is$4380 x 100/60= $7300 new price after further discount of 10%$4380 x 90%= $3942 amount saved$7300 - $3942= $3358

$4380 after a 40% discount.
Original price = $4380 / (1-40%) = $4380/0.6 =$7300

further 10% discount
purchase price=$4380x(1-10%) = $3942

Amount saved=$7300 - $3942 =$3358
