Seb's salary is $x per annum. the tax system is such that seb pays a 15% flat rate of income tax on his salary. the tax system is due for reform, and politicians have suggested the following:
1. any income under $12,000 should be tax free.
2. anything above $12,000 should be taxed at 25%.
given that seb will be paying $1,500 more under the new system, calculate how much tax seb pays under the current system. you can assume that x> $12,000.

4500

Step-by-step explanation:

To find X, we use the fact that the amount of tax under the old system, increased by $1,500 will give the amount of tax payable under the new system, so we can form an equation for X as follows:

15%×X+1,500=25%×(X−12,000),

i.e.

0.15X+1,500=0.25×(X−12,000),

giving

0.15X+1,500=0.25X−3,000,

Getting X on one side gives

4,500=0.1X,

and solving for X gives

45,000=X.

So, X=$45,000.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
