An animal shelter spends $3.50 per day to care for each bird and $4.00 per day to care for each cat. makayla noticed that the shelter spent $161.50 caring for birds and cats on wednesday. makayla found a record showing that there were a total of 43 birds and cats on wednesday. how many birds were at the shelter on wednesday?

Let x = the number of birds

Let y = the number of cats

x + y = 35       y = 35 - x

4.50x + 8.50y = 221.50       Multiply the whole equation by 100.

450x + 850y = 22150

450x + 850(35 - x) = 22150

450x + 29750 - 850x = 22150

-100x = -7600

x = 76 birds

hope this helped

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
