Question

During a sale a store offered a 40% discount on a particular camera that was originally priced at $450. After the sale the discounted price of the camera was increased by 40% wat was the price of the camera after this increase ?

Answer 1

During the sale, 

     $450 x (100% - 40%)
     $450 x 60%    =   450 x 0.6 = $270 = answer 1

After the sale,

     $270 x 1.4 = $378 = answer 2
