### Lecture Description

Word problems are challenging, but rewarding once you learn how they're done! Let's take a look at another word problem. This problem deals interest rate percentages.

Problem Text: A sum of $4000 is to be invested in 2 portions, on at 4%, the other at 6%. If the interest earned with the portion at 4% exceeds the interest earned by the portion at 6% by $40, how much is invested at each rate?
