Find the rate of increase of the weekly audience at the end of week 5 and at the end of week 12. (Round your answers to one decimal place.) week 5 million/week week 12 million/week How many viewers were there in week 5? In week 21? week 5 million week 21 millionEffect of Luxury Tax on Consumption Government economists of a developing country determined that the purchase of imported perfume is related to a proposed "luxury tax" by the following formula where N(x) measures the percentage of normal consumption of perfume when a "luxury tax" of x% is imposed on it.
