After a 40% discount the cost of a sofa is $471 what was the original cost of the sofa?
sp2606 [1]

100% - 40% = 60%, meaning the discounted price is really just 60% of the original 100% price, let's say the 100% price is hmmmm "x".

if 60% of the original price is $471, what is the 100% or namely "x"?

\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 471&60\\ x&100 \end{array}\implies \cfrac{471}{x}=\cfrac{60}{100}\implies \cfrac{471}{x}=\cfrac{3}{5}\implies 2355 = 3x \\\\\\ \cfrac{2355}{3}=x\implies 785=x

Twice the sum of a number and 11 is 34.
Maru [420]

<u>Answer:</u>

  • The number is 6.

<u>Solution:</u>

  • 2(x + 11) = 34
  • => 2x + 22 = 34
  • => 2x = 34 - 22
  • => 2x = 12
  • => x = 12/2
  • => x = 6

Hence, the number is 6.

Why is it helpful to write a fraction as a percent
tatyana61 [14]
It usually helps a person to get a better idea of how much or how big something is. I'm actually not sure why, but let's use an example. You got 38 out of 43 questions on a test. when you see 38/43 you don't really know how good that score is, but if you make it a percentage (Dividing the first number by the second to get the percentage) it's 88%. You know you did well on that test.

Law Incorporation [45]

Hello, I'll try to make this as easy to understand as possible, anyways, let's begin:

Jenna lost more weight than Sarah.

Hope this helped! c:
