23.7-10=10
that r the maths
S(p) = 400 - 4p + 0.00002p^4
D(p) = 2800 - 0.0012p^3
S(p) = D(p)
400 - 4p + 0.00002p^4 = 2800 - 0.0012p^3
0.00002p^4 + 0.0012p^3 - 4p - 2400 = 0
p = $96.24
The first thing you have to do is to divide the personal income by the percen it takes up
<span>2,176.10/47=46.3
that means that 46.3 is 1% of the whole, so if we multiply it by 100 you will get the whole
</span>
46.3*100=4630
so the answer is
4,<span>630</span>
