Question: For the following function, C computes a value, where if you add millions of $ to the value, the result is the cost of implementing a city recycling project when x , as a % (not its decimal equivalent), citizens participate.

[A] Using this model, find the percentage of participation that can be expected if USD 5 million is spent on this recycling project? Set up an equation and solve algebraically. Give answer to the nearest whole percent.

[B] Using this model, determine the cost 60% of the citizens participate?
