I think the answer is b bc you do 18.15 * 30 then subtract all the taxes
Answer:
Step-by-step explanation:
2200(1+0.0225/12) raised to the power of 12(4)
2200(1.001875) raised to the power of 12(4)
2204.125 raised to the power of 12(4)
2.98771099E160
or 2.98771099 multiplied by 10 to the 160th power

Because the value of x is raised to the power of 3, x^3 is a cubed number.
and 64 is 4^3
This makes the polynomial a sum of cubes.
By <em>analytical</em> methods and <em>algebraic</em> handling and on the basis that x is increased by 25 %, we conclude that the variable x² is increased by 18.75 %.
<h3>How to determine the percentage increase rate </h3>
In this case we have a <em>linear</em> variable x, whose increase is described by the following expression:
y = x · (1 + r/100) (1)
Where r is the <em>increase</em> rate.
If we square (1), then we find that:
y² = x² · (1 + r/100)² = (1 + r'/100) (2)
Where r' is the <em>equivalent increase</em> rate.
(1 + r/50 + r²/10000) = (1 + r'/100)
r'/100 = r/50 + r²/10000
r' = r/2 + r²/100
If we know that r = 25, then the equivalent increase rate is:
r' = 25/2 + 25²/100
r' = 18.75
By <em>analytical</em> methods and <em>algebraic</em> handling and on the basis that x is increased by 25 %, we conclude that the variable x² is increased by 18.75 %.
