Question: 290

2. An art club of 4 boys and 5 girls makes craft projects. If the boys average 2 projects each and the girls average 3 projects each, what is the total number of projects produced by the club?

  • A. 14
  • B. 23
  • C. 26
  • D. 54

Correct Answer: B

Explanation:

B Use two Average Pies to organize the information in this question-every time you see the word average draw an Average Pie . The first pie represents the information about the boys: 4 boys average 2 projects each, so place 4 in the # of items place and 2 in the average place. To find the total number of projects the boys complete, multiply 4 and 2 to find a total of 8 projects. Repeat this same process with the girls in the second pie. The 5 girls average 3 projects each, so place these numbers in their respective places in the Average Pie, and multiply to find a total of 15 projects. The question asks for the total number of projects in the class, so 8 + 15 = 23. The correct answer is (B).
