Question

An electronics store obtains their retail prices by adding a 34% mark-up to the wholesale price. Find the wholesale price of a computer that has a retail price of $513.

Answer 1

The whole price at electronics store is $338.58

Explanation:

Given as :

The markup percentage = d = 34%

The retail price = m.p = $513

Let The wholesale price = $ s.p

Now, According to question

markup percentage =
`(m.p - s.p )/(m . p)` × 100

Or, d =
`(m.p - s.p )/(m . p)` × 100

Or, 34 =
`(513 - s.p )/(513)` × 100

Or,
`(34 )/(100)` = 1 -
`( s.p )/(513)`

Or,
`( s.p )/(513)` = 1 -
`(34 )/(100)`

Or,
`( s.p )/(513)` =
`(100 - 34 )/(100)`

Or,
`( s.p )/(513)` =
`(66 )/(100)`

Or, s.p =
`(66 )/(100)` × 513

∴ s.p =
`(66* 513)/(100)`

i.e s.p = $338.58

So, The wholesale price = s.p = $338.58

Hence, The whole price at electronics store is $338.58 Answer
