Mrs. Johnson bought a ping- pong table at Academy . She saved $69 because the pingpong table was on sale for 30% off its regular price. What was the regular price of the ping -pong table?

Respuesta :

Answer:

The regular price of the ping-pong tables is $98.57

Step-by-step explanation:

Given as :

The selling price of the ping-pong table = s.p = $69

The sale discount percentage = 30%

Let The regular market price of ping-pong table = m.p = $x

Now, From discount method

Discount % = [tex]\dfrac{m.p - s.p}{m.p}[/tex]

or, 30% = [tex]\dfrac{x - 69}{x}[/tex]

or, [tex]\dfrac{30}{100}[/tex] = 1 - [tex]\dfrac{69}{x}[/tex]

Or, [tex]\dfrac{69}{x}[/tex] = 1 -  [tex]\dfrac{30}{100}[/tex]

Or, [tex]\dfrac{69}{x}[/tex] = [tex]\dfrac{100 - 30}{100}[/tex]

Or, [tex]\dfrac{69}{x}[/tex] = [tex]\dfrac{70}{100}[/tex]

Or, x = [tex]\frac{100\times 69}{70}[/tex]

x = $98.57

So, regular market price = x = $98.57

Hence The regular price of the ping-pong tables is $98.57  Answer
