Answer:
Yes that is the correct answer
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

We know that
<span>4 1/2----------> (4*2+1)/2--------> 9/2
(2/3)*(9/2)------> 18/6--------->3 yd (</span><span>this is what Trisha has )</span>
<span>if she has (2/3) she only needs (1/3)
</span><span>
[</span>the minimum amount of fabric she must buy]=(9/2)*(1/3)=1.5 yd
the answer is
