The correct Option is (C) 5x(3x^2 + 4)
Explanation:
15x^3 + 20x
Take common terms out:
5x(3x^2 + 4) Which is option C.
Write an equation system based on the problem
We can write the equation for "Twice the price in Japan minus five times the price in India is $20.60" as
∴ 2j - 5i = 20.6 <em>(first equation)</em>
We can write the equation for "Thirty cents less than three times the lowest price is thirty cents" as
∴ 3i - 0.30 = 0.30 <em>(second equation)</em>
Solve the equations
First, solve the second equation to find the price in India
3i - 0.3 = 0.3
3i = 0.3 + 0.3
3i = 0.6
i = 0.6/3
i = 0.2
Second, solve the first equation by subtitution of the value of i to the equation
2j - 5i = 20.6
2j - 5(0.2) = 20.6
2j - 1 = 20.6
2j = 20.6 + 1
2j = 21.6
j = 21.6/2
j = 10.8
The price in India is $0.20 and the price in Japan is $10.80
Answer: $80,735
=======================================================
Work Shown:
33% = 33/100 = 0.33
33% of 120,500 = 0.33*(120,500) = 39,765
Michael pays $39,765 in taxes
This makes his net pay to be 120,500-39,765 = 80,735 dollars.
------------
A shortcut is to compute
0.67*(120,500) = 80,735
The 0.67 refers to the fact that if he pays 33% of his gross income, then he keeps the remaining 100% - 33% = 67% of it.
