The chart is incorrect because it calculates 40% of 34 instead of 40 percent of x (we got 85% for our answer but I'm using x as the unknown number) results in the number of 34.
Percentage of 40% of what number = 34?
40% of what number = 34 is equivalent to: 40% × ? = 34
--------------------------
40% × ? = 34
? =
34 ÷ 40% =
34 ÷ (40 ÷ 100) =
(100 × 34) ÷ 40 =
3,400 ÷ 40 =
85
Proof:
If 40% × 85 = 34 =>
Divide 34 by 85...
... And see if we get as a result: 40%

2/1
We want a denominator of 4 so multiply by 4/4
2/1 * 4/4 = 8/4
Oh this is a great question. For future reference, the formula for this would be called an exponential growth or decay function, here it Is;
Y = a( 1+r )ˣ or Y = a( 1 - r )ˣ
the answer could be found by plugging your numbers into these equations
For example:
Y = 15,250 ( 1 - .075)⁶
A value = starting value of object
R value= decimal equivalent of percent increase or decrease
x value = number of years it has been
