Question

place all of this fleet expense information into one final cost function where y is total fleet expenses, and x is number of miles driven. write out the formula in y = m(x) b format.

Answer 1

The final cost function for fleet expenses is y = 0.09x + 35.25, where y is the total fleet expenses and x is the number of miles driven.

Step-by-step explanation:

To place the fleet expense information into a cost function in the form y = mx + b, we need to determine the slope (m) and the y-intercept (b). The slope (m) represents the rate of change in expenses per mile driven, and the y-intercept (b) represents the fixed expenses unrelated to the number of miles driven.

From the given information, we have the slope (m ≈ 0.09) and the sum of the median x values (1264) and the sum of the median y values (219.5). Substituting these values into the formula y = mx + b, we can solve for the y-intercept (b).

The final cost function is y = 0.09x + 35.25, where y is the total fleet expenses and x is the number of miles driven.
