What we are saying here is 136 students represent the rest of the students which is 100% minus 15% or 136 represents 85%. All we need to do ( there are several ways but I prefer this one) divide 136 by 85 then multiply by 100 to find answer which is 160
Let's say that Robbie's age is represented by r and Sheila's age is represented by s. Since we know that r is greater than s, we can set up a difference equation of r - s = 12. We also know that r + s = 42. Now, we can simply add the two equations and get that 2r = 54, then finally that r = 54. Therefore, Robbie is 54 years old.
Hope this helps!
