Solve the problem.Since 2011, compact SUV sales have been on the rise, while sedan sales have decreased. Let V(t) represent the number (in millions) of SUVs sold during the year that is t years since 2007. Let S(t) represent the number (in millions) of sedans sold during the year that is t years since 2007. The equations for V and S are given below.V(t) = 0.12t - 0.22 SUVs
S(t) = -0.10t + 1.43 Sedans
i) What are the slopes of V and S? What do they mean in terms of car sales?ii) Estimate in which year the same number of SUVs were sold as sedans. How many were sold of each?
What will be an ideal response?
i) The slopes of V and S are 0.12 and -0.10, respectively. This means that compact SUV sales are increasing by 120 thousand cars per year and sedan sales are decreasing by 100 thousand cars per year.
ii) In 2015, the sales for SUVs and sedans were both 680,000.
