Riley doesn't want to wait that long before purchasing the refrigerator, so she decides to consider using credit. After speaking with a store clerk, Riley learns that she qualifies for a
special payment plan the store offers. Why should Riley should consider the amount of interest
associated with the payment plan?

- "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."

histogram would be best to show the volunteer totals for each clinic and how they differ to each other.

multiply each number by ten to get a simplified answer of 7/1.
