Please explain why E over C.

In my understanding, region P has the least range of dollar amount for living expanses in four categories. So transportation cost is 16% of total expanses.

Let's calculate the range of each region:
1. Region P: 60 - 10 = 50
2. Region Q: 55 - 13 = 42
3. Region R: 64 - 8 = 56
4. Region S: 60 - 10 = 50
5. Region T: 50 -16 = 34
6. Region U: 63 - 13 = 50

The above calculation indicates that Region T has the lowest range. Therefore, the answer is option E 20%.

Can you please extend the explain of the calculation of the range? Why do you take the highest percent minus the lowest percent of each region?

I am confuse maybe for the definition of range, or what I understand a range is.

Thanks for your attention

Why do we take the range of the percents when it’s asked for range of dollar amounts? This would be ok if the total dollar spend was the same right? But in the current case, the total spends are different

You cannot. You must multiply the difference in percentages with the total dollar value of spends.

So I came up with the same way of solving it, but I guess in number 5 should be: 5. Region T: 50 - 14= 36. That's the only comment that I have with that solution. Thank you =)
