Harvey mows lawns in his spare time for extra income. buyers of his service are willing to pay $50 per lawn for as many lawns as harvey is willing to mow. on a particular day, he is willing to mow the first lawn for $25, the second lawn for $30, the third lawn for $45, and the fourth lawn for $60. assuming harvey is rational in deciding how many lawns to mow, his producer surplus is

a) $40.
b) $10.
c) $25.
d) $50.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
