Let's call the width 
and the length 
based on this, we can make two equations based on the first and second sentences in the problem.
If we substitute 
for into the second equation, we can make the following:
- Use the Distributive Property
- Subtract 4 from both sides
- Divide both sides by 4 and simplify
Now, let's find :
The length of the rectangle is 
and the width of the rectangle is 
.
Answer:
80n+20=total cost
Step-by-step explanation:
We don't know the value of n, but we don't need it for an expression. We know that the family has to pay $80 per night that they stay at the hotel. Modeling this would look like: 80n (80*n for nights). Also, we know that the family MUST pay a $20 fee. So, we can add that on to the expression to look like this, 80n+20=total cost.
Hope this helps!
Have a nice evening.
