Calculating the Total Number of Swans in the Zoo

To find the total number of swans in the zoo, we can follow these two simple steps:

1. Calculate the Number of Black Swans: - Let's denote the number of black swans as B. - According to the given information, the number of black swans is 15 less than the number of white swans. Therefore, we can express the number of black swans as: B = (35 - 15).

2. Calculate the Total Number of Swans: - The total number of swans in the zoo is the sum of the white and black swans. We can express this as: Total = Number of White Swans + Number of Black Swans.

Now, let's calculate the total number of swans in the zoo using the given information.

Calculation

1. Calculate the Number of Black Swans: - B = 35 - 15 - B = 20

2. Calculate the Total Number of Swans: - Total = 35 (white swans) + 20 (black swans) - Total = 55

Therefore, there were 55 swans in total at the zoo.
