How many times louder is a 60 dB sound than a 10 dB sound?

The problem you must solve is:

You are applying for a mortgage for $150,000 to buy a house. You shop around and find these two possible mortgage options:
•A 20 year mortgage loan with an APR of 6%.
•A 30 year mortgage loan with an APR of 5%.
1.What are your monthly payments with each loan? .
2.How much will you pay over the life of each loan? How much of that is interest?.
3.Which option would you choose? Explain your reasoning, taking into account your answers to both (1) and (2). .

To get full credit for this write-up, you should:
1.Answer all parts of the problem..
2.Show your justification for every step in your solution. Use clear, mathematically accurate language..
3.Label all numbers with the units they represent (e.g., 0.3048 ft/meter)..
4.Clearly state your conclusions using complete English sentences (for example, “Jill needs to add 43 gallons of water to her pool”)..

You may use ideas from the discussion board, but you are expected to write your solution using your own words to explain your reasoning. The report should be no more than 3 pages.
