Question

The list price of an item is $550 and it is chain discount by 50%

less 10% less 20%. How much is the discount?
$352
$198
$440
$110

Answer 1

$352

Explanation:

first discount = 550 : 2 = $275

Second discount:

10 : 100 = x : 275

x = (2750/100) = $27,50

275 - 27,50 = $247,50

third discount

20 : 100 = x: 247,50

x = (247.50*20)/100 = $49,50

247,50 - 49,50 = $198 (final price)

total discount = 550 - 198 = $352
