Answer: $1000 and the discount is $250
Step-by-step explanation:
I assume that $750 is the already discounted price, and that the unit is $.
So let x be the original price.
Setting up an equation:
750 = 75x/100; x = 1000
You can either subtract 750 from 1000 or find 25% of it, either way the discount is $250
Hope that helps!
