The linear equation Y = a + bX is often used to express cost formulas. In this equation: a) the b term represents variable cost per unit of activity.
b) the a term represents variable cost in total.
c) the X term represents total cost.
d) the Y term represents total fixed cost.

a) the b term represents variable cost per unit of activity.

Step-by-step explanation:

If X is the number of units

Y is the total cost

a is the fixed cost

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
