Hi All,
While this question is 'thick', it can be solved with note-taking, TESTing VALUES and some basic arithmetic."
We're told that "A certain grocery purchased X pounds of produce for P dollars per pound."
X = 2 pounds of produce
P = 3 dollars per pound (cost)
So (2)(3) = $6 was spent to buy this produce
Next, we're told that "Y pounds of the produce had to be discarded due to spoilage and the grocery sold the rest for S dollars per pound...."
Since we only had 2 pounds of produce to begin with, and we still need to sell some produce.....
Y = 1 pound of produce spoiled
S = 7 dollars per pound (sell price or remaining produce)
So (7)(2-1) = $7 revenue from selling the 'good' produce
We're asked for the GROSS PROFIT on the sale of the produce. $7 - $6 = $1 of gross profit.
While the answer choices look 'thick', they actually have several 'pieces' in common, so you can use that to your advantage (notice how XP and (X-Y) show up several times - you can do each of those calculations ONCE and then plug the result into multiple answers and save some time).
Answer A: (1)(7) - (2)(3) = 7-6 = 1 This IS a match
Answer B: (1)(3) - (1)(7) = negative. Not a match.
Answer C: (4)(1) - 6 = negative. Not a match
Answer D: 6 - 7 = negative. Not a match
Answer E: (1)(4) = 4. Not a match
Final Answer:
