A computer store buys a computer system at a cost of $561.00. The selling price was set at $ 935, but after a year the computer did not sell. The store then advertises a 40 % markdown on the $935 computer system. Find the sale price.

Step-by-step explanation:

First, convert the 40% to a real mathematical number. For percents, this is always done by dividing the 40% by 100%, or 40% / 100% = 0.400.

Second, find out what 40% of $935 is. This is the amount of the sale discount. This is always found by mulitplying 0.400 by the item's cost $935, like this:

0.400 x $935 = $374.00.

So for this sale, you'll save $374.00 on this item.

This means, the cost of the item to you is

$935 - $374.00 = $561.00.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
