This problem is a store purchased a digital camera and marked it up 100 % from the original cost of $863 .57.
00:07
A week later, the store placed the digital camera on sale for 40 % off.
00:11
What was the discount price? so first we'll worry about how we marked it up 100 % from the original cost of $863 .57.
00:18
And then we'll deal with the putting on sale for 40 % off last.
00:22
Because if we're going to mark up the original price, our original price of $863 .57 cents will multiply by 1.
00:30
Which will represent 100 % of the original price, plus whatever the markup is in its decimal form from percentage.
00:37
So if we're going to mark it up 100%, 100 % as a decimal is one.
00:42
So what we are doing is $863 .57 times 1 plus 1, which is 2.
00:49
And that will give us the new cost that it is being displayed for in the store after the 100 % markup.
00:55
And that value comes out to $1 ,727 ,000...
