Answer 2

Calculating the Number of Animals Arriving at the Zoo After Renovation

To calculate the number of animals that arrived at the zoo after the renovation, we can use the information provided about the number of trips made before and after the renovation, as well as the increase in the number of animals.

Step 1: Calculate the Number of Animals per Trip Before and After Renovation

Before the renovation, 150 trips were made, each carrying the same number of animals. After the renovation, 170 trips were made, each also carrying the same number of animals.

Step 2: Determine the Increase in the Number of Animals After Renovation

After the renovation, 800 more animals were brought to the zoo compared to before the renovation.

Calculation

Let's denote the number of animals per trip before the renovation as *x*.

Before the renovation: - Number of trips: 150 - Total animals before renovation: 150 * *x*

After the renovation: - Number of trips: 170 - Total animals after renovation: 170 * *x* + 800

To find the number of animals per trip and the total number of animals after the renovation, we can solve the equation: 170 * *x* + 800 = 150 * *x*

Solution

Solving the equation: 170 * *x* + 800 = 150 * *x* 20 * *x* = 800 *x* = 40

So, after the renovation, each trip carried 40 animals.

Final Answer

After the renovation, the zoo received: 170 trips * 40 animals per trip = 6800 animals.
