No problem! 
Okay you must set and equation. 
$40 × ? = 10 
I used multiplication because when things are discounted, they are multiplied by decimals 
? = [tex] \frac{10}{40} [/tex]
[tex] \frac{10}{40} [/tex] is equal to [tex] \frac{1}{4} [/tex]

1/4 is 25%
The item needs to be marked down 25% to buy and get a discount of $10
Well basically you have to divide 10 into 40 and that would be 1/4 of 40 so you would need 25% to get the lamp at 10 dollars.
