Answer:
a. $2,600,000
b. $2,500,000
Explanation:
The computation is shown below:
a. The additional revenue raised by State A is
= Revenue after applying the tax rate - initial revenue after applying the tax rate
where,
Initial revenue after applying the tax rate = $800 million × 5% = $40 million
And, the Revenue increased after applying the tax rate is
= $710 million × 6%
= $42.6 million
So, the additional revenue is
= $42.6 million - $40 million
= $2,600,000
b. The additional revenue raised by State Z is
= Sales tax rate × service volume
= 5% × $50 million
= $2,500,000
