b) Select the formula for the price, in dollars, as a linear function of the time in months since February 2009. The answer is letter
a. Price = $578 - $10(t)
b. Price = $350 - $8(t).
c. Price = $349 - $10(1)
c) Find a formula for the price in dollars, as a linear function of the time in months since February 2009. Using this formula, the price in January 2012 which is
35 months after the Kindle was launched will be s
