Emma buys and sells truck parts. she bought two tires for $35 each and later sold them for $65 each. she bought three rooms for $75 each and later sold them for $136 each. she bought five headlight covers for four dollars each and later sold them for $15 each what is emma’s total profit

first you do 65 subtracted by 35 and that is 30 and then you do 136 subtracted by 75 and that is 61 so you add 61 and 30 and you get 91 then 91 plus 15 and then that is 106 and that is your answer

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.
