Hello! So to solve this question, we can write and solve a proportion. We write the proportion as change/original = x/100, where change is the distance between two number and the original is the previous number. Percents are parts of 100, so x is a percentage out of 100%. 1,435 - 1,220 is 215. Now, set it up like this.
215/1,435 = x/100
Cross multiply the values to get 21,500 = 1,435x. Divide each side by 1,435 to isolate the "x". 21,500/1,435 is 14.9825783972 or 15 when rounded to the nearest whole number. The percent change in the number of 8th graders is about 15%.

Answer:
The fencing will cost $330.09
Step-by-step explanation:
First we have to calculate the perimeter of the semicircle for that we use the following formula:
d = diameter = 29ft
s = semicircle
π = 3.14
s = d * 1/2 * π
we replace the values that we know
s = 29ft * 1/2 * 3.14
s = 45.53ft
Now we multiply the number of feet by the price of what comes out 1 foot of fence
45.53 * $7.25 = 330.0925
Round to the nearest hundredth
$330.0925 = $330.09
