Answer 2

Task 358: Finding the Number of Stamps in the Third Album

To solve this problem, we can use the following expression: Total number of stamps in the third album = Total number of stamps - (Number of stamps in the first album + Number of stamps in the second album)

Let's calculate the number of stamps in the third album for y = 40, 45, and 62.

For y = 40: Number of stamps in the third album = 180 - (95 + 40) = 45 For y = 45: Number of stamps in the third album = 180 - (95 + 45) = 40 For y = 62: Number of stamps in the third album = 180 - (95 + 62) = 23 So, the number of stamps in the third album for y = 40 is 45, for y = 45 is 40, and for y = 62 is 23.
