Say initially, Franklin's wage was $x and after the increase, it is $y. Thus, Franklin's wage increased by (y - x)*100%/x.BTGmoderatorDC wrote:Franklin's wage increased by what percent?

We have to get the value of (y - x)*100%/x.
Let's take each statement one by one.
(1) Franklin's wage after the increase was $45,000.
=> y = 45,000. We do not know the value of x. Insufficient.
(2) Franklin's wage increased by $2,000.
=> y - x = 2,000. We do not know that value of x. Insufficient.
(1) and (2)
From y - x = 2,000 and y = 45,000, we have x = 43,000.
Thus, Franklin's wage increased by (y - x)*100%/x = 2,000*100%/43,000 = a unique value. Sufficient.
The correct answer: C
Hope this helps!
