How many birds were at the shelter?

Question

An animal shelter spends $4.50 per day to care for each bird and $6.50 per day to care for each cat. Kaylee noticed that the shelter spent $96.00 caring for birds and cats on Thursday. Kaylee found a record showing that there were a total of 16 birds and cats on Thursday. How many birds were at the shelter on Thursday?

Answer 1

B+C = 16

4.5b + 6.5c = 96

B+C = 16

45b + 65c = 960

45b + 65(16 - b) = 960

45b + 1040 - 65b = 960

-20b = -80

b = 4

4 birds and 12 cats
