# 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?

Result

b =  19
c =  21

#### Solution:

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

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

b = 19
c = 21
