Multiple Choice

There are 20 animals in the barn. Some are geese and some are buffalo. There are 64 legs in all. How many of each animal are there?

12 geese and 8 buffalo

8 geese and 12 buffalo

4 geese and 28 buffalo

The buffalo all sat on the geese and now there are only 44 legs in all.

Multiple Choice

There are 15 animals in a barn. These animals are horses and chickens. There are 44 legs in all. Which system of equations represents the situation?

x + y = 15
4x + 2y = 44

4x + 2y = 15
x + y = 44

x = 2y + 44
4x = y + 15

2x - 4y = 44
x - y = 15
