A manufacturer estimates that she can sell a maximum of 100 thousand cell phones in a city. By advertising heavily, her total sales grow at a rate proportional to the distance below this upper limit. If she enters a new market, and after 4 months her total sales are 18 thousand phones, find a formula for the total sales (in thousands) t months after entering the market, and use this to estimate the total sales at the end of the first year. Total sales at end of the first year: thousand phones Give your answer to at least 1 decimal place

The amount of solar power installed in the US can be modelled as M(x) = 15.45(1.46*) megawatts, where x is the number of years since 2000. This model tells us that: In 2000, there 15.45 megawatts installed, and the amount is growing by 146% per year In 2000, there were 15.45 megawatts installed, and the amount is growing by 46% per year In 2000, there were 1.46 megawatts installed, and the amount is growing by 1545% per year In 2000, there were 1.46 megawatts installed, and the amount is growing by 15.45% per year.
