CJ, KJ, and AJ collect stamps. CJ has 5 more than twice the number of stamps that KJ has, and KJ has half as many as AJ. If the three boys have 930 stamps all together, how many stamps does AJ have? Let's be accurate as possible.
Let x represent the number of stamps for AJ. KJ:x / 2 stamps. CJ:5 + 2(x / 2) = 5 + x. Total:x + (x / 2) + 5 + x = 930. (5 / 2)x + 5 = 930. (5 / 2)x = 925. x = 925(2 / 5) = 370 stamps.
The answer: 370.
