Answer: Choice D) $x = a\left(1-\frac{y}{b}\right)$

================================================

Work Shown:

$\frac{x}{a}+\frac{y}{b} = 1\\\\\frac{x}{a} = 1-\frac{y}{b}\\\\x = a\left(1-\frac{y}{b}\right)\\\\$

Explanation:

First I subtracted y/b from both sides. Then I multiplied both sides by 'a' to fully isolate x. You can optionally distribute the 'a' through to each term inside the parenthesis, but your teacher has chosen not to do this.

we first determine the amount of accrued interest to be earned;

interest = 275000 - 32000

= 243000

Applying the simple interest formula;

$I=\frac{P*R*T}{100}\\243000=\frac{32000*R*10}{100}\\ 243000=3200R\\R=75.9375$
