1,250 an 15% sale an 6.5 sales tax

Given:

price = 1,250

sales discount = 15%

sales tax = 6.5%

The problem is unclear whether the price is the original price or the discounted price. I am assuming that the price is the original price.

Original price times sales discount rate is the value of sales discount

1,250 x 15% = 187.50

Original price less the value of sales discount is the discounted price.

1,250 - 187.50 = 1,062.50

Discounted price times sales tax rate is the value of the sales tax

1,062.50 x 6.5% = 69.06

Discounted price plus sales tax is the total cost of the purchase

1,062.50 + 69.06 = 1,131.56
