Animal Count in the Zoo

In a small zoo, there are three types of animals: lions, zebras, and giraffes. The relationship between the numbers of these animals can be described as follows:

- There are twice as many zebras as lions.

- The total number of giraffes is 10 less than the total number of lions and zebras combined.

If there are 15 lions in the zoo, how many animals are there in total?
