Answer:

C) \frac{x+3}{x}

Step-by-step explanation:

The given expression is

\frac{\frac{x}{x-3} }{\frac{x^2}{x^2-9} }

We rewrite to obtain:

\frac{x}{x-3} \div \frac{x^2}{x^2-9}

Multiply the first fraction by the reciprocal of the second to get;

\frac{x}{x-3} \times \frac{x^2-9}{x^2}

Factor the numerator using difference two squares;

\frac{x}{x-3} \times \frac{x^2-3^2}{x^2}

\frac{x}{x-3} \times \frac{(x-3)(x+3)}{x^2}

Cancel out the common factors to get;

\frac{1}{1} \times \frac{(1)(x+3)}{x}

This simplifies to;

\frac{x+3}{x}

Answer:

YTM = 5.45%

Step-by-step explanation:

Here, we are interested in calculating the yield to maturity.

Mathematically;

Annual coupon=1000*4.3%=43

YTM=[Annual coupon+(Face value-Present value)/time to maturity]/(Face value+Present value)/2

=[43+(1000-870)/18]/(1000+870)2

=5.45%
