Answer:

y= 500+7x

Step-by-step explanation:

Given data

Total amount for the rent=  $500

Cost of food per night= $10

Family charges per night=$60

Let the number of nights be x

and let the total charges be y

Hence, the expression for the situation is given as

y=500+10x+60x

y= 500+7x

Step-by-step explanation:

<u>Step 1: Define</u>

<u />\displaystyle \frac{x^2 - 10x - 24}{x^2 - 3x - 108}<u />

<u />

<u>Step 2: Simplify</u>

  1. [Fraction] Factor numerator:                                                                           \displaystyle \frac{(x - 12)(x + 2)}{x^2 - 3x - 108}
  2. [Fraction] Factor denominator:                                                                       \displaystyle \frac{(x - 12)(x + 2)}{(x - 12)(x + 9)}
  3. [Fraction] Divide:                                                                                              \displaystyle \frac{x + 2}{x + 9}

We know that <em>x</em> cannot equal -9 because we would get a divide by 0 (undefined) error. We also know that <em>x</em> cannot equal 12 because it was canceled out when simplifying.
