Question

the cost of producing a number of items x is given by c = mx + b, in which b is the fixed cost and m is the variable cost of producing one more item. if the fixed cost is 190 and the variable cost is 10, what is the cost equation?
A. c = 10x - 190 B. 190 =10x C. c =190x +10 D. c =10x +190

Answer 1

c =10x +190

Answer 2

y =mx+b y=c; m=variable =10; b=fixed=190
then c=10x+190

Answer 3

so the ans is D

Answer 4

C = 10x + 190
