Question

I need help ASAP
On number 2

Answer 1

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. 

Answer 2

No problem!
Okay you must set and equation.
$40 × ? = 10
I used multiplication because when things are discounted, they are multiplied by decimals
? =
`(10)/(40)`

`(10)/(40)` is equal to
`(1)/(4)`

1/4 is 25%
The item needs to be marked down 25% to buy and get a discount of $10
