What was the discount if something was $200 and is now $150

Answer: 25% off

Step-by-step explanation:

1) divide $150 by $200

2) That comes to. 75, meaning $150 is 75% of $200

3) But you want to know how much was disounted, so you have to subtract. 75 from 1 to get. 25, meaning 25% was taken off the sale price
