Teddy saved $63.00 when he bought a CD player on sale at his local electronics store.  If the sale price is 35% off the regular price, what was the regular price of the CD player? ​

Answer 1

Given:-

• Teddy saved ₹63.00 when she bought a CD player on sale at his local electronics store.

• The sale price is 35% off the regular price.

To Find:-

• Regular price of the CD player.

Solution:-

Here, Let the regular price of the CD player be ₹$x$ .

Now, According to the Question,

⇒ $\sf{x + x \ \times \dfrac{35}{100} = x + 63}$

⇒ $\sf{x + \dfrac{7x}{20} = x + 63}$

⇒ $\sf{\dfrac{20x + 7x}{20} = x + 63}$

⇒ $\sf{\dfrac{27x}{20} = x + 63}$

⇒ $\sf{27x = 20 (x + 63)}$

⇒ $\sf{27x = 20x + 1260}$

⇒ $\sf{27x - 20x = 1260}$

⇒ $\sf{7x = 1260}$

⇒ $\sf{x = \dfrac{1260}{7}}$

⇒ $\underline{\boxed{\tt{x = 180}}}$

$\rm{Hence,\ The\ regular\ price\ of\ the\ CD\ player\ is\ Rs.\ 180.}$

⇢ x + 7x/20 = x + 63

⇢ 20x + 7x/20 = x + 63

⇢ 27x/20 = x + 63

⇢ 27x = 20(x + 63)

⇢ 27x = 20x + 1260

⇢ 27x - 20x = 1260

⇢ 7x = 1260

⇢ x = 1260/7
