The total cost, CCC, in dollars, to produce bbb books is given by the equation above. What is the meaning of 1.51.51, point, 5 in the equation

Complete question :

C = 1.5b + 67.5

The total cost, C, in dollars, to produce b books is given by the equation above. What is the meaning of 1.5 in the equation

An additional $1.5 for each book produced

Step-by-step explanation:

The equation given : C = 1.5b + 67.5 ; takes the form of a linear equation; where C = cost of production ; b = number of books ;

The general form of a linear equation is given as :

y = mx + c

from the general formula; m = gradient or slope which is the change in the x variable per unit change in the y variable

Hence comparing with the equation given ;

1.5 is the slope or gradient ;

1.5 refers to the increase in production cost per increase in the number of books produced.
