There is a 10% off sale on laptop computers. If someone saves $35 on a laptop, what was its original cost?

IceJOKER [234]

Answer:

The original cost is $350

Step-by-step explanation:

Let's assume

original cost of computer is x

There is a 10% off sale on laptop computers

So, amount saved is

$=\frac{10}{100}x=0.10x$

now, we are given

someone saves $35 on a laptop

so, we can set them equal

and then we can solve for x

$0.10x=35$

we can divide both sides by 0.10

and we get

$x=350$

So,

The original cost is $350

The time between seeing the lightning and hearing the thunder is s seconds. The distance d you are from lightning is approximate

leonid [27]

The direct variation that can be established using the given parameters is that, the time it takes between seeing the lightning and hearing the thunder is directly related to the speed.

However, it can also be established that the time described above is inversely proportional to the distance. This can be written as,
t = k/d
We substitute the given expression for each of the known terms. t is time, s, and d is distance, 3s.

s = k/3s

The k written in the equation is the constant of proportionality.
