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.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
