How much interest will it pay over the 10 years period? b) A sum of $50,000 is invested in a savings account which pays interest at a rate of 9% per year compounded annually. If the amount is kept on deposit for 16 years, what will the compound amount equal? How much interest will be earned during the 15 years? c) A local University is planning to invest $500,000 every 3 months in an investment which earns interest at the rate of 15% per year compounded annually. The first investment will be at the end of this current quarter. i) To what sum will the investment grow at the end of 5 years? i) How much interest will be earned during this period?

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

a) The major Airline is planning to purchase new airplanes. It wants to borrow $800 million by
issuing bonds. The bonds are for a 10-years period with simple interest computed quarterly at
a rate of 2% per quarter. Interest is to be paid each quarter to bondholders. How much will the
