I believe she will have 8 rolls of toilet paper left after one year.
She started with 36, then gave away 4, so then she would have 32 left for herself, then she used 2 every month so if you deduct 2 rolls every month for 12 months she would use 24 in one year. So 32-24 is 8.
Answer:
6 bags.
Step-by-step explanation:
We have been given that trail mix is sold in 1-pound bags. Mary will buy some trail mix and repackage it so that each of the 15 members of her hiking club gets one 2/5 bag.
Let us find the number of pounds Mary will need to give to 15 members. As Mary wants to give 2/5 of 1 ounce bag of trail mix, so she will need 15 times 2/5 ounces to given to 15 members of her hiking club.



So Mary needs 6 pounds of trail mix to give to 15 members of her hiking club. As trial mix is sold in 1-pound bags, therefore, Mary should buy 6 bags to have enough of trail mix without any trail mix left over.
