The number of cars to minimize the cost

310 cars

Step-by-step explanation:

The given function that models the cost is :

The function is of the form:

where a=0.4 , b=-248 and c=55,514

The minimum cost occurs at:

We substitute to get:

Therefore 310 cars must be made to minimize cost.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
