Answer:
The percent of change in 6 yards to 36 yards is 500% .
Step-by-step explanation:
Formula

Where
Change in value = Final value - initial value
As given
The percent of change in 6 yards to 36 yards.
Final value = 36 yards
initial value = 6 yards
Change in value = 36 - 6
= 30 yards
Put in the formula


Percentage = 500%
Therefore the percent of change in 6 yards to 36 yards is 500% .
So you have to solve for "donation" - so let's call that X. And the things we know are what the grandfather donated, as a function - meaning based upon - Theo's donation. We'll call that Y.
So Y is equal to 1/2 of $4 plus Theo's donation...... 0.5*(x+4).
So... 4.25 = 0.5(X+4), solving for X
4.25=0.5x + 2
-2 -2
2.25=0.5x - divide each side by 0.5 to get x alone.
x = 4.50
Plugging back in:
(4.50 + 4.00)*0.5 = 4.25!
