Dr. Fritz, a cat and dog veterinarian, examined 40% cats this week at his clinic. If Dr. Fritz examined 22 cats, how many cats and dogs did he examine altogether?
A 60
B 55
C 44
D 9
If 40% of the animals he examined were cats, then 60% were dogs. Since 22 represents 40%, he examined 100%/40% x 22 = <<100/40*22=55>>55 animals in total.
So, the answer is letter B, 55.
