Question

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?

Answer 1

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

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 % =
`(m.p - s.p)/(m.p)`

or, 30% =
`(x - 69)/(x)`

or,
`(30)/(100)` = 1 -
`(69)/(x)`

Or,
`(69)/(x)` = 1 -
`(30)/(100)`

Or,
`(69)/(x)` =
`(100 - 30)/(100)`

Or,
`(69)/(x)` =
`(70)/(100)`

Or, x =
`(100* 69)/(70)`

∴ x = $98.57

So, regular market price = x = $98.57

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