✔ 最佳答案
Let the cost price be x dollars.x (1+20%) = 600
x (120%) = 600
x = 600 / 120%
x = 500
Therefore the cost price is $500.

既然商店有20% profit,cost 怎會比selling price高?換言之$720一定不是答案.
2006-12-15 22:15:56 補充：
Cost price + profit = selling priceorCost price x (1 + profit %) = selling price

The cost price is:
600/(1+20%)
=600/120%
=$500
OR
Let the cost price be x./Let x be the cost price.
(1+20%)x=600
120%x=600
x=600/120%
x=500
.:The cost price is$500
The follow up method also can use,you can use equation or the simple's method.
Hope can help you!

Let the cost of model car be $X,
So,
cost + profit = $600
$X + ($X x 20%) = $600
$X x (1.2) = $600
so that,$X = $600 / 1.2=$500
The cost of the model car is $500.!

$600 x(1 + 20% )
= 600 x 1.2
= $720
= 600 x 1.2
= $720
