Question

An animal shelter spends $1.00 per day to care for each bird and $7.00 per day to care for each cat. Oliver noticed that the shelter spent $186.00 caring for birds and cats on Wednesday. Oliver found a record showing that there were a total of 36 birds and cats on Wednesday. How many birds were at the shelter on Wednesday?

Answer 1

x= # of birds
y= # number of cats

x+y=36
y=36-x
1(x)+7(y)=186
x+7(36-x)=186
252-6x=186
x=11

11 birds at the shelter on Wednesday
