Answer 1

Answer:

the cost price of a product is the amount incurred in total to produce or manufacture the given item

to find the cost price of the computer, assuming that this dealer is the manufacturer, the following is the procedure:

profit= selling price - cost price

let the cost price be c

the selling price

10%discount

discounted price =100% (marked price)- discount (10%)= (90%)

90%/100%*22000

0.9*22000

$19800

the discounted price is the selling price

therefore profit = 19800-c

%profit=profit/cost price *100%

19800-c/c*100%=20%

100(19800-c)/c=20

1980000-100c =20c

120c=1980000

c=1980000/120

c=$16500

therefore the cost price of the computer is $16500
