Question

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

Answer 1

There were 16 birds at the shelter on Wednesday.

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
