Question 1181722
you can't solve this problem for the tax or the tax rate because you need one to get the other.


the cost of the item is 142.
the selling price is 161.15
the profit is 161.15 - 142 = 19.15


you will be taxed on the profit of 19.15.


in order to find the tax, you need to know the tax rate.


in order to find the tax rate, you need to know the tax.
if you don't have one, you can't solve for the other.


the formula for tax is T = P * R


T is the tax
P is the profit
R is the tax rate


if the profit is 19.15, the formula becomes T = 19.15 * R
if you don't know R, then you can't find T.


if you take this formula and solve for R, it becomes R = T / 19.15
if you don't know T, then you can't find R.


if you don't know either, then you can't solve the problem.
