It is 2x(x-7)+3(x-7) = (2x+3)(x-7)
Let be t the tax,
so the <span>tax on the item with a price p is:
t=(12 x p) /100
</span><span>the total price of the item, including tax
let be T=</span>the total price, including tax
so T= t+p, where <span>t=(12 x p) /100
</span>so T = 112p/100
he total price, including tax, of an item that costs 75.
by using T = 112p/10<span>0,
</span>we can get T= 112 x 75 / 100, T=84
the problem is not difficult, so as fo me it is obvious
