Using an interest table gradient series factor, write the Present Worth $($at EOY $0)$ of the following series of payments. Interest is $5\%.$

$\backslash$table$[[$EOY$,0,1,2,3,4,5],[$NCF $$,-1000,500,600,700,800,900]]$

A bonus package pays an employee $$1000$ at the end of the first year, $$1500$ at the end of the second year, and so on$,$ for the first nine years of employment. What is the present worth of the bonus package at $6\%$ interest?

Assume you borrowed $$50,000$ at an interest rate of $1$ percent per month, to be repaid in uniform monthly payments for $30$ years. In the $163$rd payment, how much of it would be interest, and how much of it would be principal?

Consider two mutually exclusive alternatives:

$\backslash$table$[[$Year$,$Alternative A$,$Alternative B$],[0,-5000$$$,-5000$$
