3 red oaks at $ 390.00 each + 1 red oak at 80% off $ 390.00 + 8.25 % tax (3*390 + .2*390)*1.0825 is the total amount she paid under the sale conditions.

ok :)

Directrix (directrix):

Without the sale, she would have paid: (4*390)*1.0825 =

Directrix (directrix):

Then, subtract 1350.96 from 1688.70 to get how much she saved: 1688.70 - 1350.96 =
