This problem is difficult to explain, but I will try my best.
First, divide both sides by 2304 to isolate the squared part (1+(x/100))^2
This gets you 196=(1+(x/100))^2
Then, you square root both sides. Luckily, 16 is the square root of 196, which makes it a lot easier.
16=1+(x/100)
Subtract both sides by 1 and multiply both sides by 100.
15=x/100
x=1500 Hope this helps.
