Calculating the Number of Magnets in Tanya's Collection

To calculate the number of magnets in Tanya's collection, we can use the information provided in the question.

Given: - Tanya's collection has more than 120 but less than 140 magnets. - 2/3 of all the magnets depict city views. - 20% of the magnets depict animals.

Solution:

Let's denote the total number of magnets in Tanya's collection as x.

From the given information: 1. 2/3 of the magnets depict city views, which means (2/3)x magnets depict city views. 2. 20% of the magnets depict animals, which means 0.20x magnets depict animals.

We can express the total number of magnets in Tanya's collection using the given information: x = (2/3)x + 0.20x

Now, we can solve for x: x = (2/3)x + 0.20x x = (2/3 + 0.20)x x = (0.20 + 0.6667)x x = 0.8667x

To find the exact value of x, we can use the given range of Tanya's collection, which is more than 120 but less than 140.

Calculation:

Let's calculate the range of Tanya's collection: - If x > 120 and x < 140, then the number of magnets in Tanya's collection is between 120 and 140.

Conclusion:

Based on the given information, the number of magnets in Tanya's collection is between 120 and 140.
