Maria’s family hosts a barbeque every month in the summer. In May, they bought 3.2 pounds of hamburger and 3 packages of hot dog
Sindrei [870]
Given:

May:
hamburger: 3.2 pounds * 4.25 = 13.60
hotdogs:     3 packages * 4      = 12
Total cost: 13.60 + 12 = 25.60

June:
hamburger: 3.2 pounds * 1 1/2 = 4.8 pounds * 4.25 = 20.4
hotdogs:      3 packages * 1/3    = 1 package * 4        =   4
Total cost: 20.4 + 4 = 24.4

25.60 - 24.40 = 1.20

They spent more on May by $1.20. Choice C.

Option D:

$y=\frac{5x-2}{x}

Solution:

Given function:

$y=\frac{-2}{x-5}

To find the inverse of the function.

<u>Inverse of a function:</u>

<em>If a function f(x) is mapping x to y, then the inverse function of f(x) maps y back to x.</em>

$y=\frac{-2}{x-5}

Interchange the variables x and y.

$x=\frac{-2}{y-5}

Now, solve for y.

Multiply both sides by (y - 5).

$x(y-5)=-\frac{2}{y-5}(y-5)

Cancel the common factors, we get

x(y-5)=-2

Divide by x on both sides.

$y-5=-\frac{2}{x}

Add 5 on both sides.

$y=-\frac{2}{x}+5

$y=-\frac{2}{x}+\frac{5}{1}

To make the denominator same, multiply the 2nd term by \frac{x}{x}.

$y=-\frac{2}{x}+\frac{5x}{x}

$y=\frac{-2+5x}{x}

$y=\frac{5x-2}{x}

Option D is the correct answer.
