Question

An animal shelter spends $5.00 per day to care for each bird and $8.50 per day to care for each cat. Nicole noticed that the shelter spent $132.50 caring for birds and cats on Tuesday. Nicole found a record showing that there were a total of 23 birds and cats on Tuesday. How many birds were at the shelter on Tuesday?

Answer 1

the answer is 18 birds and 5 cats

Explanation:

the easiest way i did this was that i used a calculator and kept subtracting 8.5 untill i reached a number that was completely divisable by 5, i subtracted 8.5 five times which got the total down to 90$ and since each bird is 5$ you can just divide which means there was a total of 18 bird and 5 cats on Tuesday
