Cierra paid $375 for a chair. the price of the
chair mary purchased was the price cierra
paid. how much did mary pay for her chair?

$300

Step-by-step explanation:

im not sure how to explain it but its kind of like a riddle. The second person always ends up paying or getting less of the first person. :D

- "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."
