Question

An animal shelter spends $4.50 per day to care for each cat and $8.50 per day to care for each dog. Nora noticed that the shelter spent $235.00 caring for cats and dogs on Thursday. Nora found a record showing that there were a total of 30 cats and dogs on Thursday. How many cats were at the shelter on Thursday?

Answer 1

Answer: There were 5 cats on Thursday.

Explanation:

4.5x + 8.5y = 235

x + y = 30: y = 30-x

4.5x + 8.5(30-x) = 235

4.5x + 255 - 8.50x = 235

-4x = 235-255

x = 20/4 = 5

y = 30-5 = 25

So, 4.5 (5) + 8.5 (25) = 235

Answer 2

There were 9 cats at the shelter on thursday.
