Astore has clearance items that have been marked down by 55%. they are having a sale, advertising an additional 20% off clearance items. what percent of the original price do you end up paying?

Step-by-step explanation:

60

%

discount given in total, so only  

40

%

is paid.

Explanation:

So here we need to make a two-step changing factor.

This means that we first take  

0.5

(something decreasing by  

50

%

) times  

0.8

(something decreased by  

20

%

) which is  

0.4

(something decreased by  

60

%

- "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."
