An animal shelter

An animal shelter spends $5.50 per day to care for each bird and $8.50 per day to care for each cat. Nicole noticed that the shelter spent $283.00 caring for birds and cats on Wednesday. Nicole found a record showing that there were a total of 40 birds and cats on Wednesday. How many birds were at the shelter on Wednesday?

Correct result:

b =  19
c =  21

Solution:


b+c = 40
5.50 b + 8.50 c = 283.00

b+c = 40
5.50•b + 8.50•c = 283.00

b+c = 40
5.5b+8.5c = 283

b = 19
c = 21
