9.99x3x (1+6%) = $28.5913

Sean Roach · Answer 2

The answer is: 28.59

Solution:

Total cost before tax and discount:

9.99 x 3 = 29.97

total discount:

29.97 x 0.10 = 2.997

total cost - discount:

29.97-2.997=26.973

Tax:

26.973 X 0.06 = 1.61838

Total cost plus tax:

26.973 + 1.61838 = 28.59138 round to only 2 decimals: 28.59
