Answer: try to (x) each one by the answer to -0.0035 +70
Step-by-step explanation:
There are 540 fuses in total and the original price of the internet is $55.91
<h3>
How to work with percentages?</h3>
a) We know that 5% of the fuses are faulty, and there are 27 faulty fusses, then we can write:
5% = 27
100% = x
We want to find x, to do that, we can write:
x = 27*(100%/5%) = 27*20 = 540
There are 540 fuses in total.
b) Now we know that the original price is P, and when we decrease it by 7%, then new price is $52.00
Then we can write:
$52.00 = P*(1 - 7%/100%)
$52.00 = P*(0.93)
$52.00/0.93 = P = $55.91
The original price is $55.91

Step-by-step explanation:
Answer:
and 
Step-by-step explanation:
Given:
The rational equation to solve is given as:

We use the cross multiplication rule and multiply the numerators one side with the denominators of the other side. Therefore,

Now, for
, the rational equation is equal to 0. So,
is a solution.
Also,
is also a solution as the equation's denominator is defined at that point.
So, no extraneous solution.
