Question

In sam's pet corner, there are puppies and parrots, the total of 15 heads and 50 feet. How many parrots and how many puppies?

Answer 1

Let x be the number of puppies (each of which has 4 feet) and y be the number of parrots (each of which has 2 feet). The equations that would best represent the question are,
x + y = 15
4x + 2y = 50
The values of x and y are 10 and 5, respectively. Therefore, there are 10 puppies and 5 parrots.
