1) A store manager uses a markup rate of 28% on all
televisions. What is the markup on a television
which cost the store $300?
A) 894 B) 548 C)$84 D) $384

D, $384

Step-by-step explanation:

Original price: $300

If the price raised by 28% then we are adding 28% more to $300.

.28 x 300 = 84

300 + 84 = $384

a² + b²= c²

24² + 7² = c²

c= 25

- "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."
