$85 bill before tax<br> Discount:25%<br> Tax:6.4%
Radda [10]

Answer:

$67.83

Step-by-step explanation:

Price before tax: $85

Discount: 25%

100% - 25% = 75% = 0.75

Price after discount: 0.75 * $85 = $63.75

Tax: 6.4%

100% + 6.4% = 106.4% = 1.064

Price after discount & tax: 1.064 * $63.75 = $67.83

Answer: $67.83
