The change as a percentage is 6.7 %
<h3>
How to calculate the percentage change ?</h3>
The price of the building in the year 2021 is $4,200,00
The price of the building in 2021 is $4,500,000
Therefore the percentage change can be calculated as follows
= 4,500,000 - 4,200,000/4,500,000 × 100
= 300,000/4,500,000 × 100
= 0.066 × 100
= 6.7 %
Hence the percentage change is 6.7%

Using vertical angles, it is found that:
A. The solution for y is of y = 4.
B. The angle measures are given as follows:
<h3>Vertical Angles</h3>
If two angles are opposite by the same vertex in crossing segments, these angles are called vertical angles, and they are congruent, that is, they have the same measure.
In the context of this problem, the angles of 6y + 42 and of 66 are vertical, hence the value of y is calculated as follows:
6y + 42 = 66
6y = 24
y = 24/6
y = 4.
Angles A and C are supplementary, meaning that the sum of their measures is of 180º, hence:
<C + 66º = 180º
<C = 180º - 66º
<C = 114º.
Angles C and D are vertical, hence the measure of angle D is calculated as follows:
<D = 114º.

Answer:
Interest in 3 years = $456.52
Step-by-step explanation:
As we know the the formula of compound interest
Total amount = ![A(1+\frac{r}{n})^{nt}](https://tex.z-dn.net/?f=A%281%2B%5Cfrac%7Br%7D%7Bn%7D%29%5E%7Bnt%7D)
Here n = number of times amount is compounded
r = rate of interest
t = period
Here A = $2500
r = 0.0575
n = 1 (compounded annually)
t = 3 years
Therefore amount after 3 years
![P=2500(1+\frac{.0575}{1})^{3}](https://tex.z-dn.net/?f=P%3D2500%281%2B%5Cfrac%7B.0575%7D%7B1%7D%29%5E%7B3%7D)
P =2500(1.0575)³
= 2500×1.18
= $2956.52
We have to calculate the interest then
Interest = $2956.52-$2500 = $456.52
So after 3 years interest gained = $456.52
