How do you solve number 15 ? i’m having a big trouble

Hello there! There is a 20% discount, and I also explained how you can solve this problem.

Okay, so the question is asking you how much the discount is if a price that is originally marked as $0.75 is on sale for $0.15. Basically, you're trying to find what percent of $0.75 is equal to $0.15.

To do this, you can set up an equation that models the situation:

Next, we cross multiply. (This means we are multiplying x by 0.75 and 100 by 0.15)

(0.75)x = (100)(0.15)

0.75x = 15

Now, we isolate x by dividing both sides of the equation by 0.75.

15/0.75 = 20

So, the discount is 20%.

I hope this helps and have a great rest of your day!
