Answer:

Part A) The percentage increase was $6.1\%$

Part B) Michael is financially better off this year than last year

Step-by-step explanation:

Part A)

we know that

Using proportion

Let

x-----> the percentage increase

$\frac{100\%}{33,000}=\frac{x\%}{35,000-33,000}\\ \\x=2,000*100\%/33,000\\ \\x=6.1\%$

Part B) Compare the percentage increase with the inflation

$6.1\%>5\%$

The percentage increase is greater than the inflation

therefore

Michael is financially better off this year than last year

Answer:

The correct option is D.

Step-by-step explanation:

The given expression is

$(4-\sqrt{7})(4+\sqrt{7})$

Difference of two squares property:

$a^2-b^2=(a+b)(a-b)$

Using the above property, the given expression can be written as

$(4)^2-(\sqrt{7})^2$

Applying square we get

$16-7$

$9$

Therefore the correct option is D.
