1 answer:

8 0

1+7 and 7+1 are the same equations. The numbers are just switched around .
Example:
1+2=3
2+1+3

They add up to the same answer no matter where they are placed, therefore knowing 1+7 helps you find the sum of 7+1 (again, because they are the same)

Answer:

Step-by-step explanation:

$ 86,000 lies in the category $84201 - $ 160725

Tax = 14,382.50+ 24% of the amount over $84,200

Amount over $84,200= 86,000 - 84,200 = $1,800

Tax for the amount $ 1,800 =24% * 1800 = 0.24 * 1800

= $ 432

Tax for the amount $86,000 = 14382.50 + 432

=$ 14814.50
