Step-by-step explanation:

Jocelyn wants to buy 4 red oak trees using the promotion buy 3 and get the fourth at 80% off.

The regular price for a red oak tree = $390.00

Tax rate = 8.25%

The price of an oak tree with taxes = 390 +(8.25% × 390)

                                                           = 390 + (0.0825 × 390)

                                                           = 390 + 32.175 = $422.175

Jocelyn paid 20% of the price of fourth tree and she saved 80% of the amount =

80% of 422.175

= 0.80 × 422.175

= $337.74

Jocelyn ended up saving $337.74 by using the promotion.
