Reiny,
The present value of Mr. Wang's offer is
$65000
the present value of Ms Macrae's offer is
13000 + 5800(1.00625)^24 = 62944.37
the difference between the two values is
$2055.63
looks like they rounded to the nearest dollar.

Reiny,
For these type of question, my students always had to make a "time graph"
Then you decide on a fixed date, in this case "now", and move each money entry to that fixed date, either forward or backwards using the formula
principal(1+i)^n
if n is positive the money would move to the right
if n is negative the money would move to the left.
