Answer: A. . . . . . . . . .
I can’t do that check mark thing so I’ll use ! instead.
!12+2!8-12!2
!12 2!8
2!3+2!8-12!2
!8 2!2
2!3+2x2!2-12!2
2x2!2 4!2
2!3+4!2-12!2
2!3+(4!2-12!2)
2!3-8!2
M=3n
divide both sides by 3
M/3=3n/3
on the left hand side, the numerator constant cuts the denominator 3
therefore, n=M/3
5/100=0.05
0.05*45.90=2.295
$2.30 is the tax. Feel free to correct this If wrong.
