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?

the answer is 18 birds and 5 cats

Step-by-step 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

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
