Jimmy works part-time at walmart earning $11 per hour. he is allowed to work anywhere between 0 to 30 hours per week. his only expense is $8 per week for an unlimited bus pass. the function e(h) = 11h − 8 represents his weekly earnings for h hours. a. evaluate e(10) and interpret the meaning in context of the problem. b. evaluate e(15) and interpret the meaning in context of the problem. c. interpret the statement e(10) < e(15)

- "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."
