The city of St. John's is intalling a new swimming pool in the east end recreation centre. One design being considered is a reinforced concrete pool that will cost $5,400,000 to install. Thereafter, the inner surface of the pool will need to be refinished and painted every 5 years at a cost of $440,000 per refinishing. Assuming that the pool will have essentially an infinite life, what is the present worth of the costs associated with the pool design? The city uses a MARR of 10%. If the installation costs, refinishing costs, and MARR are subject to 5% or 10% increases or decreases, how is the present worth affected? (NOTE: Text answers are case sensitive and every field in this question is worth equal value) All calculations are performed using 4 significant figures. (a) Complete the table below:
