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

Answer:

The whole price at electronics store is $338.58

Step-by-step 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 = $\dfrac{m.p - s.p }{m . p}$ × 100

Or, d =  $\dfrac{m.p - s.p }{m . p}$ × 100

Or, 34 = $\dfrac{513 - s.p }{513}$ × 100

Or,  $\dfrac{34 }{100}$ = 1 -  $\dfrac{ s.p }{513}$

Or,  $\dfrac{ s.p }{513}$ = 1 -   $\dfrac{34 }{100}$

Or, $\dfrac{ s.p }{513}$ =  $\dfrac{100 - 34 }{100}$

Or, $\dfrac{ s.p }{513}$ =  $\dfrac{66 }{100}$

Or, s.p =  $\dfrac{66 }{100}$ × 513

∴  s.p = $\frac{66\times 513}{100}$

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
