Final answer:
The correct model for the cost of supplying recycling bins to p% of the population is B) C = 250p, which results from simplifying the given model 25,000p/100.
Step-by-step explanation:
The cost C (in dollars) of supplying recycling bins to p% of the population in a rural township is modeled by the expression 25,000p/100. This simplifies the expression to C = 250p, which means that for every 1% of the population served, it costs $250.
If you compare the simplified model with the provided options, the correct answer is clearly B) C = 250p because the other options either do not include the correct unit conversion from percentage to a decimal (100% = 1 as a decimal) or they represent different scales of cost not aligned with the question.
