15) The Feldmans bought their first house for $20,000. Over the years they moved three times into bigger and bigger houses. Now, 37 years later, they are ready to retire and want a smaller house like the first one they bought. If inflation in property values has averaged 3.7% per year during that time, how much will such a house cost them now? (Round your answer to the nearest dollar.) Show your work.

step-by-step explanation:

a.) list the factors of 40.

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.
