Kofi electronic bought a shipment of Tv's at a net price of $477.36 each, after a discount of 15%,10% and 4%. What is the list price ?

Answer

15% discount= $561.60

10% discount= $530.40

4% discount = $490.25

step by step

_15% discount_

85% sale percent =$477.36

The list price is 100%

If more less divide

(100/85) * $477.36

=$561.60

_10% discount_

90% sale percent =$477.36

The list price is 100%

If more less divide

(100/90) * $477.36

=$530.40

_4% discount_

96% sale percent =$477.36

The list price is 100%

If more less divide

(100/96) * $477.36

=$497.25

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
