ANSWER:

The "light from a star" that is "8 light years" takes 8 Earth years to reach "Earth".

EXPLANATION:

Light travels at an "incredible speed" of "300,000 kilometers per second".

The distance between any two objects that are far spread in the universe is measured in either speed of light or astronomical unit (AU).

If the distance of the star is "8 light years" away from our "planet", and divide it with the value of speed of light you get 8 earth years.

scZoUnD [109]

Answer:

412.8

Explanation:

The price of one set of sheet is

$p=129$

Here Carla wants to buy 8 sets of sheets; however, there is a 2x1 discount, this means that the price she pays will be the price of only 4 sets of sheets, so:

$P=4p=4(129)=516$

However, we are also told that there is an additional 20% discount.

The amount of the discount is:

$d=0.20P = 0.20(516)=103.2$

So the discounted price will be:

$P'=P-d=516-103.2=412.8$

So, Carla will pay 412.8 soles.
