Avery leaves his house at 6:00 a.m. to go for a 6- mile run and returns to his house at 7:09 a.m. Describe the distance d (in miles) Avery runs as a linear function of his run time t (in minutes). Assume Avery runs at a constant pace. Submit your answer for the equation of the line in exact form. For instance, if the slope of the line is 1 then enter the slope in fractional form and not 6 1 as the approximation ≈ 0.1667. 6 Provide your answer below: d(t) =
An elementary school is taking a busload of children to a science fair. It costs $140.00 to drive the bus to the fair and back, and the school pays each student's $4.00 admission fee. a). Express the trip's cost C(n) as a linear function of the number of children n who make the trip. (Use lower-case letter n.)C(n) = b). Identify the slope and y-intercept of your linear function. m = b = c). Solve for n when C(n) = 164.n = d). Calculate C(15).$ e). Explain in practical terms what C(15) means.C(15) represents the cost of the science fair trip if ______ children make the trip.
