At 9:30 am tomorrow, we open our doors for the last time. The price of every item in the store will be reduced 10% every hour, on the hour, beginning at 10am until everything goes, The stereo calvin would love to buy is $359 dollars.. Calvin has saved $270 for the stereo. Henry told calvin that at 11:01 am, the price of the stereo will be $287.20. Jacob says $290.79 will be the price. What might he expect the price to be at 11:01 and why? Henry claims that since the prices go down 105 every hour, after 10 hours, the stereo will be free. He tells calvin to arrive at the store at 8pm for a free stereo. Do you agree with Henry's reasoning? Explain why and why not. Sales tax is 6%. Assuming he gets no more money, explain to Calvin when he will be able to afford the stereo and how you figured this out. Be sure your work is shown in an organized format so that it can be easily followed

Question 569498: Hi,
1. suppose that the sum of the measures of the vertex angles of a polygon is 1620 degrees. How many sides does the polygon have?
what I've tried:
(n-2)180/n= i multiplied "n" by both sides to cancel out the fraction and then use distribution property to fix the equation.
180n - 360= 1620n
-180n 180n
-360= 1440n
-0.25=n
but that is the wrong answer. the book says that the answer of sides is 11.
Please help me.
