The lesson to remember is this: read the text slowly and carefully, with a finger on the screen if necessary. Especially because once something is misread, it often stays misread. Earn up to 56 profit selling the finest quality chocolate bars and candy bar fundraisers in the fundraising industry. On exam day a misreading like this can lead to a wrong answer or waste a LOT of time. The misreading lead to to the equation 0.45n = 0.3n, reworking my steps, then rereading the statement, and discovering the problem. It should have been a quick question too, if I hadn't misread Statement 2 as 'If the club had sold 80% more candy bars.'. This is a fairly straightforward question (despite the 700 tag). Total gross profit would be (0.25)(n+80) = (20% more than the original gross profit) = (1.2)(0.25n) $0.25 gross profit on each bar, total gross profit = 0.25n The statement tells us nothing about the number of candy bars.

Solve to get: total number of candy bars sold = 400 In other words: 80 = (0.2)(total number of candy bars sold) If the sale of 80 more candy bars would have increased profits by 20%, then 80 represents 20% of the total number of candy bars sold. Since we can answer the target question with certainty, statement 2 is SUFFICIENT If the ACTUAL gross profits are $100, and since each candy bar sold results in a gross profit increases of $0.25, the total number of candy bars sold = $100/$0.25 = 400 If this $20 increase represents a 20% INCREASE in gross profits, then the ACTUAL gross profits must be $100 (since $20 is 20% of $100) So, selling 80 more candy bars results in a gross profit increase of $20 Twix was the first candy bar to combine Milk Chocolate, caramel, and cookies. Initially made in Britain, Mars Canada makes the Canadian version. Twix Bars consists of two cookie bars with a layer of caramel and coated in milk chocolate. Statement 2: If the club had sold 80 more candy bars, its gross profits would have increased by 20 percent.įor every candy bar sold, the gross profit increases by $0.25 Mars Canada makes the Canadian version of Twix bars. Since we cannot answer the target question with certainty, statement 1 is NOT SUFFICIENT In this case, the answer to the target question is the club sold 2 candy bars In this case, the answer to the target question is the club sold 1 candy barĬase b: The selling price of one candy bar = $150, and the club sold 2 candy bars. If you're not convinced, consider these two possible cases:Ĭase a: The selling price of one candy bar = $300, and the club sold 1 candy bar.

Revenue = (number of candy bars sold)(selling price for a candy bar)Īs you might imagine, there are many different solutions to this equation. Let n = the TOTAL number of candy bars sold So, x + 0.25 = selling price of one candy bar (in dollars) Let x = the wholesale cost of one candy bar (in dollars) Statement 1: The total revenue from the sale of the candy bars was $300. Given: The club made a gross profit of $0.25 for each candy bar it sold Target question: How many candy bars did the club sell? (2) If the club had sold 80 more candy bars, its gross profits would have increased by 20 percent. (1) The total revenue from the sale of the candy bars was $300. If a club made a gross profit of $0.25 for each candy bar it sold, how many candy bars did the club sell?
