Question 1190432
<br>
The question doesn't ask for any ages; it only asks for an expression for Lou's age in terms of x, which is Bob's age.<br>
x = Bob
(1/3)x = Jenny (Bob is 3 times as old as Jenny)
(1/15)x = Lou (Jenny is 5 times as old as Lou)<br>
(1/15)x+10 = Lou's age in 10 years<br>
None of the given answer choices is equivalent to that, so the problem is faulty.<br>
