Jen Murphy’s average monthly expenditure for forcieris was $169.40 for the first quarter this year. In April she spent 201.35 an

lara [203]

Given that the average expenditure of 3 months is $169.40.

In April, Jen spent = $ 201.35

In May, she spent = $ 158.10

Let she spent in June =$x

Then, the average monthly expenditure of these three months is given by:

$\frac{201.35+158.10+x}{3}=169.40\\ \\201.35+158.10+x=169.40*3\\\\201.35+158.10+x=508.2\\\\359.45+x=508.2\\\\x=508.2-359.45\\\\x=148.78$

So, she can spend $148.75 in June and still maintain the average expenditure.

If y=3/x then y'=? A)-y/x B)y/x C)-x/y D)-3x/y E)-y/3x

$y=\dfrac{3}{x}\\\\\\
y'=\left(\dfrac{3}{x}\right)'=(3\cdot x^{-1})'=3\cdot(x^{-1})'=3\cdot(-1)\cdot x^{-2}=-3\cdot x^{-2}=\\\\\\=-\dfrac{3}{x^2}=-\dfrac{3}{x\cdot x}=-\dfrac{3}{x}\cdot\dfrac{1}{x}=-y\cdot\dfrac{1}{x}=-\dfrac{y}{x}$
