An animal shelter spends $4.00 per day to care for each bird and $6.50 per day to care for each cat. olivia noticed that the shelter spent $212.00 caring for birds and cats on thursday. olivia found a record showing that there were a total of 38 birds and cats on thursday. how many birds were at the shelter on thursday?

There were 14 birds

Step-by-step explanation:

Be

x = number of birds

y = number of cats

4$*x + 6.5$*y = 212$  (total spent on thursday)

x + y  = 38  (total number of birds and cats)

y = 38 -x

4$*x + 6.5$*(38 -x) = 212$

-2.5$ x = -35$

x = 14 (number of birds)

y = 24 (number of cats)

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
