   So 9C3 ways. 9! / (9-3)! = 9! / 6! = 504 ways</span>

the government removes a $4 tax on buyers of restaurant meals and imposes the same $4 tax on sellers of restaurant meals, then t
lesya692 [45]

Answer:

(B)

Explanation:

The price paid by buyers will not change, and the price received by sellers will not change because;

First,

Buyers paid 4$ tax before, later government removes or substracts -$4 tax away causing tax on meal purchased by buyers = $0.

Second,

Prior to removal of the tax on buyers of meals, sellers would have likely included this cost $4 into their cost of meals to buyers.

Now buyers are not imposed tax but the sellers are. Sellers would include this cost into the cost of meals, which is then transferred to buyers.

The equation would look this way;

Cost +$4 tax - $4 tax= + $4

The same cost would apply.
