Here's the book answer: First your told that a store sells a certain video for $32, which is 60 percent more than it costs the store. So to figure out the store's cost, translate the English into math: 32=1.6x, where x is the cost to the store. x=32/1.6=20, so the store's cost is $20. During a sale it's offered to employees at 25 percent off the store's cost, or .75*$20=$15, so $15 is the final price to the employee. But wait! the question asks what percent of the original price the employee pays, so divide 15 by 32. You should get .46875, or 46.875 percent, which you can grid as either 46.8 or 46.9.

My question is: Where did they get 1.6x from and how did they get .75*$20 from? And I really don't understand the answer so help me.

1.6 is the decimal equivalent of 160%. The store charged customers 160% of its wholesale price. 1.6x is 160% of an unknown number (the store's wholesale price).

.75*$20 is 75% of the store's cost of $20. 100% - 25% = 75%

explain how they got the whole answer. Because what you just explained to me is'nt enough.
