Answer:
Option (d) is correct.
Step-by-step explanation:
Given that,
The wholesale price of a pen is $15.
It then marks up the price by 94%.
Its marked price is equal to 94% of $15. So,
Selling price of the highlighter pen is equal to the sum of marked price and the wholesale price.
SP = $14.1+$15
SP = $29.1
Hence, the marked price is $14.1 and the selling price is $29.1
The answer is: the average height is 
, the median height is r-2.
r - Ray's height
l - Lin's height
s - Sam's height
<span>Ray is 2 inch taller than Lin: r = l + 2 </span>⇒ l = r - 2
Ray is 3 inch taller than Sam: r = s + 3 ⇒ s = r - 3<span>
</span><span>The average is the sum of all values divided by the number of values:
</span>
<span>
Since </span>l = r - 2 and s = r - 3, then:
<span>The median means the middle value. Let's first rearrange values so we can find the middle one:
</span>Ray is taller than Lin and Sam, so Ray is the tallest.
Sam is much shorter than Ray comparing to Lin, so Sam is the shortest.
Therefore, values are from the lowest to the highest:
(s, l, r)
⇒ (r-3, r-2, r)
Median of these values is in the middle, so the median height is r-2.
r - Ray's height
l - Lin's height
s - Sam's height
<span>Ray is 2 inch taller than Lin: r = l + 2 </span>⇒ l = r - 2
Ray is 3 inch taller than Sam: r = s + 3 ⇒ s = r - 3<span>
</span><span>The average is the sum of all values divided by the number of values:
</span>
Since </span>l = r - 2 and s = r - 3, then:
<span>The median means the middle value. Let's first rearrange values so we can find the middle one:
</span>Ray is taller than Lin and Sam, so Ray is the tallest.
Sam is much shorter than Ray comparing to Lin, so Sam is the shortest.
Therefore, values are from the lowest to the highest:
(s, l, r)
⇒ (r-3, r-2, r)
Median of these values is in the middle, so the median height is r-2.
