To build a helicopter you need 2 blue blocks, 4 green rods, and 1 red wheel. To build a car you need 1 blue block, 2 green rods, and 4 red wheels. Your profit margins for each toy are as follows: Airplane $7, Helicopter $8, Car $5. The parts available to you are as follows: 25 blue blocks, 29 green rods, and 30 red wheels. It is ok to have leftover parts. Question: What is the maximum profit you can achieve?
