Item that has $80 has a 20% discount and a 10% tax what is the remaining answer?
+2592 You usually apply a tax before a discount so lets do the math
Forget the price right now
10% is the same as .1 so you can write a tax of $X amount of money by writing .1X
Lets apply that to the $80.8*88 = 70.4
Y is the tax and price
Y=1.1($80)
this is 110% of the $80
Then, you take a 20% discount
Write that as .8X, it will give you 80% of the price
.8($88) = $70.40

+129907 Nice answer, Spawn........let me prove that it doesn't matter about the order in which we take the discount / tax
Taking the discount first and then applying the tax, we have
80 * .80 * 1.10 = $70.40
Taking the tax first and then applying the discount, we have
80 * 1.10 * . 80 = $70.40
The reason for this is that A*B*C = A*C* B
