Multiply number by percentage

Hi -

Might as well throw my $0.02 in.

I'm not sure which way you are trying to work this problem, so I will work it both ways:

0.33x = 11

Which means X is 33.33 as everyone agrees. But to maintain balance to the equation, you have to multiply both sides by 1.1 (or a 10% increase) which gives you:

1.1 * 0.33x = 11 * 1.1
or
0.363x = 12.1 which still equates to x = 33.33 so our formula is still valid and balanced.

I think the problem is SAYING 10% takes you from 33% to 43%, which isn't true. You can't add the two percentages. You have to multiply. So you should end up with 36.3%, not 43%.

Working the problem the other way: IF you WANT the result to BE 43% of the original number, you would have to multiply 11 by 1.3029. I get that by taking 33.33 x 0.43 = 14.3319
14.3319 / 11 = 1.3029 which is an increase of 30.29%, not 10%.

Taking percentages of percentages can get really tricky. I have to write them out as I did above.

Make sense or am I way off base?

You had a great point indeed! The thing is I want to see gradually increasing on inbound calls which means I have to watch out by playing with the increasing percentage to see the gaps of resources etc.

The 10% was just an example, what exactly I want is to be able to increase gradually from 1-67% to see the changes and also when I hit 67% on A1 to get the 100% of the number(volume).

I'm still trying to figure out how to make this real
