The school office users r reams or white paper and 3 reams of blue paper every day use distributive property to write and simplify an expression for how much paper the school office uses in one day

(500r + 1500) sheets per day.

Step-by-step explanation:

The school office uses r reams of white paper and 3 reams of blue paper every day.

Now, the total number of reams of paper that the school office uses every day will be (r + 3) reams.

Now, we know that 1 ream of paper is equivalent to 500 sheets of paper.

So, the school office uses a total 500(r + 3) sheets of paper every day.

Now, using the distributive property the total number of sheets will be = (500r + 1500) (Answer)
