At Blooming Gardens nursery, they are currently running the following promotion: Buy three trees of the same kind at the regular price and get the fourth at 80% off. Jocelyn is needing some trees for her backyard and decided to buy four red oak trees using the promotion. The regular price for a red oak tree is $390.00. Based on a tax rate of 8.25%, Jocelyn ended up saving $ by using the promotion.

Given:
Regular Price = 390.00
Discount on 4th tree = 80%
Sales tax : 8.25%

If bought at regular price:
4 * 390 = 1560
1560 * 8.25% = 128.70
1560 + 128.70 = 1688.70 total cost

If promotion is availed.
3 * 390 = 1170
1 * 390 * (1-.8) = 78
1170 + 78 = 1248
1248 * 8.25% = 102.96
1248 + 102.96 = 1,350.96 total cost

Total cost: w/o promotion and w/ promotion
1,688.70 - 1,350.96 = 337.74 SAVINGS IN USING THE PROMOTION
