Answer:
The money belongs to Paz is <u>267.30</u>.
Step-by-step explanation:
Given:
Zacarias and paz together have 756.80.
Zacarias has 489.50.
Now, to find money belongs to Paz.
Let the money belongs to Paz be ![x.](https://tex.z-dn.net/?f=x.)
The money Zacarias has 489.50.
Total money of Zacarias and paz together = 756.80.
Now, to write and solve the equation to find the money belongs to Paz:
![x+489.50=756.80](https://tex.z-dn.net/?f=x%2B489.50%3D756.80)
<em>Subtracting both sides by 489.50 we get:</em>
![x=267.30](https://tex.z-dn.net/?f=x%3D267.30)
Therefore, the money belongs to Paz is 267.30.
By using the concept and properties of percentages, we conclude that the hospital has a total of 300 beds.
<h3>How many beds are available in a hospital?</h3>
In accordance with the statement, there are 210 patients in the beds of a hospital and 30 % of the beds are available. We must take advantage of the concept of percentage to calculate the total number of beds. 210 patients occupy 70 % of the beds.
Then, the total number of beds at the hospital is determined by dividing the number of beds with patients and its respective percentage:
n = 210 / 70 %
n = 210 / (70 / 100)
n = (210 · 100) / 70
n = 300
