Find the selling price for each item.
original price of a radio: $125.60 discount: 35%
cost of a microscope: $96.25 markup: 20% tax 6%

A ) The selling price of radio is $ 81.64

B ) The selling price of microscope is $ 72.94

Step-by-step explanation:

Given as :

A ) Market price of radio = M.P = $ 125.60

Let The selling price of radio = S.P =  $ x

The discount = 35 %

So, Discount %  =

Or, =

Or, = 1 -

Or,   =  

Or,   =  

∴  x =

I.e  x = $ 81.64

So, The selling price of radio is $ 81.64

B ) The market price of microscope = M.P = $ 96.25

    The discount = 20 %

    Tax percentage = 6 %

Let the selling price of microscope = $ y

Or, =

Or, = 1 -

Or,   =  

Or,   =  

∴  y =

I,e y = $ 77

Again Tax of 6% is added

Or, $ 77 × 0.94 = $ 72.38

∴ The final cost of microscope after discount and tax is $ 72.94

Hence A ) The selling price of radio is $ 81.64
