In 2007, there were more than 8.14 million cars for sale. The number of cars then decreased by 23% per year. Write an exponentia
tatuchka [14]

Answer:

In 2013 there were approximately 2.2 million cars for sale.

Step-by-step explanation:

Since the number of cars is decreasing by 23% per year, it is a decay model. This types of decay can be expressed in the following expression:

cars(x) = cars(2007)*(1 - 0.23)^{x - 2007}

Where x is the year, cars(2007) is the number of cars in 2007. Applying this data we have:

cars(x) = 8.14*(0.77)^{x - 2007}

If we want to know the number of cars in 2013, we need to apply that value to x and solve the expression.

cars(2013) = 8.14*(0.77)^{2013 - 2007}\\cars(2013) = 8.14*(0.77)^{5} = 2.20332

In 2013 there were approximately 2.2 million cars for sale.
