Answer: 30% or $ 135.
Explanation
The mark up is generally expressed as a percentage. It is the percent increase on the cost.
We can calculate the mark up from cost to sale price of the item as a composition of steps. That is what the next steps show.
1) First step: calculate the the price after the item is marked down by 10%:
Selling price: $ 650
Mark down = 10% of 650 = 0.10 × $ 650 = $65
Price after mark down: $ 650 - $ 65 = $ 585.
2) Second step: difference of the price marked down to the cost:
$ 585 - $ 450 = $ 135
3) Calculate the percent mark up:
% mark up = (mark up / cost) × 100 = ($ 135 / $ 450) × 100 = 30%
$30 because 4 x 3 = 12 and 10 x 3 = 30
A box plot has 5 data descriptions. The correct option is 87 and 132.
<h3>How does a boxplot show the data points?</h3>
A box plot has 5 data descriptions.
- The leftmost whisker shows the minimum value in the data.
- The rightmost whisker shows the maximum value in the data.
- The leftmost line in the box shows the first quartile.
- The middle line shows the median, also called the second quartile.
- The last line of the box shows the third quartile.
Since each quartile of the box-and-whisker plot represents 25% of the data. Therefore, values between which there are 3 quartiles present will represent 75% of the data.
Hence, the correct option is 87 and 132.
