in ten years, the population increases from 20,000 to 23,000. Find the actual increase and the percentage increase.

actual amount of increase is 3000

% increase is 15%

Step-by-step explanation:

The actual amount of increase is

23,000-20,000= 3,000

To find the percent increase, take the actual amount of increase and divide by the original amount

3,000/20000=.15

Change to percent

15%

1/2/4/5/8/10/20/40

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

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

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

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

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
