For the following, assume that Plants A and B have the following marginal costs for reducing emissions:Number of units reduced Marginal costs for Plant A Marginal costs for Plant B1 3 12 5 23 7 34 9 55 11 9(a) The government tells both plants to reduce three units of output. How much does this "conventional" regulation cost each plant? Whatâs the total cost?(b) The government implements a carbon tax of $5 per unit. How much does each plant reduce? What is the total cost?(c) Which approach is cheaper? Why is the cheaper approach cheaper?

Answer body lying face up ;

Answerboth technicians (a) and (b);

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
