Tito bought a rare album for $68.00 and later sold it for $76.00 what is the percent of increase , rounded to the nearest tenth?

Percent of increase=11.8%

Step-by-step explanation:

It is given in the question that Tito bought a rare album for $68.00 and later sold it for $76.00 .

So increase in price is the difference of selling price and the buying price. That is,

And the percentage is

And that's the required answer.

- "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."
