In 30 years, sue will be 1 1/2 times as old as she is now. how old is she now? a) 15 b)20 c)45 d)60

You can use an equation to find the answer.

I'm going to use the variable x as Susie's age.

x+30=1.5x
-0.5x=-30
x=60

So, Susie is 60 years old right now, which fits in to the problem perfectly (is she's alive in 30 years...).

Hope this helps!
