let be t the tax, 
so the tax on the item with a price p is:
t=(12 x p) /100
the total price of the item, including tax
let be T=the total price, including tax
so T= t+p, where t=(12 x p) /100
so T = 112p/100

he total price, including tax, of an item that costs 75.
by using T = 112p/100, 
we can get T= 112 x 75 / 100, T=84

the problem is not difficult, so as fo me it is obvious
