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.
