⇛-7.5(x−3) = 3.75
⇛-7.5x + 22.5 = 3.75
⇛-7.5x = 3.75 - 22.5
⇛-7.5x = -18.75
⇛x = -18.75 ÷ -7.5
⇛x = -18.75/-7.5
⇛x = 2.5

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.
