Karrie bought a refrigerator from a rental center for $989.47. she makes 12 monthly payments of $97.32 with her credit card. the rental center charges $2.25 for every purchase made with a credit card. she also had to pay late fees in the amount of $55 four different times. what is the total cost of the refrigerator? mathematics

- "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."
