Roy is now 4 years older than Erik and half of that amount older than Iris. If in 2 years, Roy will be twice as old as Erik, then in 2 years what would be Roy’s age multiplied by Iris’s age?

  1. 8
  2. 28
  3. 48
  4. 50
  5. 52

Answer(s): C

Explanation:

Translate piece by piece into numbers. R (Roy) = Erik E. + 4. The second equation: R = I (Iris) + 2. The third equation: R +7 = 2(E + 7). We have three equations with three variables.
Roy is 6, Iris is 4 and Erik is 2. In four years Erik would be 6 and Iris 8, the answer is 48. The correct answer is C.



An investment yields an interest payment of $228 each month. If the simple annual interest rate is 9%, what is the amount of the investment?
