An animal shelter spends three dollars per day to take care for each bird and seven dollars per day take care for each cat alexandra noticed that the shelter spent $174 caring for birds and cats on wednesday alexandra found a record showing that they were a total of 34 birds and cats on wednesday how many birds were at the shelter on wednesday

There were 16 birds  at the shelter on Wednesday.

Step-by-step explanation:

Number of cats and birds on Wednesday = 34

let the number of birds on Wednesday = b

Then number of cats = (34 -b)

The rate of taking care of each bird in shelter = $3

The rate of taking care of each cat in shelter = $7

Total amount spent by shelter on Wednesday = $174

So, according to the question

b x ($3)  +  (34 -b) ($7) =  $ 174

or,  3b + 238 - 7b = 174

or, 4b = 64

⇒ b = 64/4 = 16

Hence, the number of birds in shelter on Wednesday = b = 16

and  Number of cats = 34 - 16 = 18
