ANSWER: 11(y+15)

WHY?:

Well first we know that there will be a sum of a number and 15. Let's put that together.

#+15

We can't leave a number sign so instead we will assign a variable. According to the answers it is y. Let's substitute # for y.

y+ 15

Now we know that this will be multiplied. Let's put parentheses around it to show that it will be times something.

(y+15)

The number it said it will be multiplied by is 11. To finalize the equation, put 11 outside of the parentheses for your final answer.

11(y+15)
