A company charting its profits notices that the relationship between the number of units sold x and the profit P is linear. If 600 units sold results in $4623 profit and 675 units sold results in $8598 profit, find the marginal profit, which is the rate of change of the profit. The marginal profit is

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.

In 1992, the cost of the operating system for a computer was $50, and in 1998 the cost was $100. Using 1990 as t = 0, derive the linear relationship between the year and cost of the software. your answers to the nearest hundredth. The y-intercept means that in the year ------the cost of the operating system was $------ The slope means that each year the cost is going up by $------
