The answer would be the first option.
6.2 percent of 300 is 18.6,
and 1.45 percent of 300 is 4.35
It makes a total of 22.95
300 - 22.95 = 277.05
First, we’re going to use this formula:
2nd number - 1st number
————————————— x 100%
1st number
If we plug in the numbers to this equation:
23-20
———- x 100%
20
And subtract 23 to 20, the answer to this equation is:
3
—- x 100% = 15%
20
In this case, the percent of increase is 15%.

So if we have 4x^2 - 27 = 0 then by using the square root properties we get:
4x^2 = 27
x^2= 27/4
x= +/- sqrt(27/4)
x=+/- 3*sqrt(3)/(2)
hope this helps! any questions please just ask! Thank you!!
