Rayhana has a coupon for 15% off a single item at a store. If the item has a regular price of p dollars, then the sale price can be represented by p – 0.15p. Which expression is equivalent?

0.85p is equivalent

Step-by-step explanation:

In this question, we are asked to find which expression is equivalent to p -0.15p, representing 15% discount off an item purchase.

We need to understand that if she is buying at 15% discount, this automatically means she is paying 85% of the price. As the price paid plus the discount would be equal to 100%.

Now let’s cost what she paid.

Mathematically, the amount paid would be 85/100 * p = 0.85p
