You mark it up 20% Price + 20% = p + 20/100p = p (1 + 0.20 ) = 1.2 p
6.45 * 1.2 = 7.74
You take off 5% which by the same reasoning (almost) means p/1.05
7.74 / 1.05 = 7.37
Now you need a sales tax
7.37 * 1.06 = 7.81 dollars.

Answer:
x = 12
Step-by-step explanation:
we can put this is a proportion: (new side 1) / (old side 1) = (new side 2) / (old side 2)
so in this case, 18 would be old side 1, x would be new side 1
12 would be old side 2, and 8 would be new side 2
plug these in: x/18 = 8/12
cross multiply 18 and 8: x = 144/12
now simplify: x = 12
