A coin sold at auction in 2017 for $3,158,000. The coin had a face value of $2 when it was issued in 1786 and had previously been sold for $420,000 in 1971. a. At what annual rate did the coin appreciate from its first minting to the 1971 sale? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e. g., 32.16.) b. What annual rate did the 1971 buyer earn on his purchase? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e. g., 32.16.) c. At what annual rate did the coin appreciate from its first minting to the 2017 sale? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e. g., 32.16.)

A) future value = present value (1 + rate)ⁿ

420,000 = 2 (1 + r)¹⁸⁵

420,000 / 2 = (1 + r)¹⁸⁵

210,000 = (1 + r)¹⁸⁵

¹⁸⁵√210,000 = 1 + r

1.06848 = 1 + r

1.06848 - 1 = r

r = 0.06848 or 6.85%

B) future value = present value (1 + rate)ⁿ

3,158,000 = 420,000 (1 + r)⁴⁶

3,158,000 / 420,000 = (1 + r)⁴⁶

7.519 = (1 + r)⁴⁶

⁴⁶√7.519 = 1 + r

1.04483 = 1 + r

1.04483 - 1 = r

r = 0.04483 or 4.48%

C) future value = present value (1 + rate)ⁿ

3,158,000 = 2 (1 + r)²³¹

3,158,000 / 2 = (1 + r)²³¹

1,579,000 = (1 + r)²³¹

²³¹√1,579,000 = 1 + r

1.0637 = 1 + r

1.0637 - 1 = r

r = 0.0637 or 6.37%

a manufacturer of printed circuit boards uses exponential smoothing with trend to forecast monthly demand of its product. at the end of december, the company wishes to forecast sales for january. the estimate of trend through november has been 200 additional boards sold per month. average sales have been around 1000 units per month. the demand for december was 1100 units. the company uses α = 0.20 and β = 0.10. make a forecast including trend for the month of january.

the answer is true.  i do believe this is the answer because of the amount of wrecks people get into each year.  if you double this with avoiding those so said wrecks, that would make you a "skilled" driver.
