care for each cat. Noah noticed that the shelter spent $52.00 caring for birds and cats

on Friday. Noah found a record showing that there were a total of 19 birds and cats

on Friday. How many birds were at the shelter on Friday?

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.
