Could you please explain assist me with getting the answer to these finance questions using the formula explanations to get the answers?  I am having trouble following the example provided in my text.  Thanks

1. In discussing a possible loan with the firm’s banker, Smith found that the bank is willing to lend Dellvoe up to $800,000 for one year at a 9% simple, or quoted, rate. However, he forgot to ask what the specific terms would be.
2. Assume the firm will borrow $800,000. What would be the effective interest rate if the loan were based on simple interest? If the loan had been an 8% simple interest loan for six months rather than for a year, would that have affected the EAR?
