Basically what the question is asking you is to explain whether or not it is the responsibility of educational leaders to prohibit (ban) tobacco around or near their property...it wants you to use evidence and stuff like that to support your answer...so just write whether or not you think it's their job and find evidence why or why not to help support it

A good way to figure out the answer is if you say the sentence out loud and try each answer choice in the sentence (for future reference)
The answer would be 54.50 because 2.24x3=6.72 and 16x1.79=38.64 and you would need 6 packs of hearts and 6x3.19=19.14 and all that equals $54.50.
