Richard has just returned from his holiday in Bolandia. Before he left he exchanged $300 into
bols (Ъ). To make the exchange, a fixed amount of money (the commission) was taken off the
$300 and then the remaining money was exchanged for Ъ540. When he got back, Richard had
Ъ180 left, which he exchanged back into dollars. This time the Ъ180 was exchanged into dollars
first and then the commission was taken off, leaving Richard with $60. The commission charges
and exchange rates were the same at both exchanges.
If Richard had exchanged $500 at the start of his holiday, how many bols would he have
received?
A Ъ840
B Ъ900
C Ъ940
D Ъ1000

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
