Answer:
9000
Step-by-step explanation:
67.50 x 2 x 12 = 1620 (deduction for the whole yr)
1620 / 18 x 100 = 9000
The standard form of any linear equation with two variables is

, where a, b, and c are constants. To convert this equation to standard form, simply subtract

from both sides to get

We could leave it in this form, though, in this case, it might be better at if we multiplied both sides by -1 to get
The only type of symmetry is
vertical line of symmetry
