I know that sacrificing certain amounts of money on a specific category grants the Sun Temple certain boosts and attacks, with the maximum being $50,000 in each category.

I was wondering, what is the easiest way to hit this 50,000 for each category?

By easiest I mean the least number of towers to hit as close to the target as possible,
such as will a 5-2-0 Dart Monkey and a 0-2-5 Tack Shooter hit the $50,000 Primary class requirement?
Or will it be too little, or maybe way too much?
