the depreciation method to be used is the 10-yr period for the cost of the containers to be amortized That would be the equivalent uniform annual cash flow for 10 years of the cost of the containers at t=0

Exercise 1 The city of Des Moines, IA is considering implementing a program to recycle solid waste materials that currently end up in a landfill. The program involves distributing plastic containers, one per household. Each container costs $30, and there are 108,652 households in Des Moines currently The city gets 25% of the revenue from the sale of recyclable solid wastes, and the company that manages the recovery operation keeps the rest. The estimated total revenue from recyclable solid wastes is estimated to be $850,000 per year. The smaller volume of disposable solid waste materials will extend the life of Des Moines' landfill, resulting in a benefit of $350,000 per year for the citizens of Des Moines. If the containers are amortized over a 10-year period at 7% per year, calculate the B/C ratio and say if the City of Des Moines should implement such program Exercise 1 The city of Des Moines, IA is considering implementing a program to recycle solid waste materials that currently end up in a landfill.
