Each box holds 5 pencils. 7 boxes have been filled. Write/solve an inequality that shows how many more pencils she will need in order to fill at least 15 boxes.

Answer- x is greater than or equal to 40. But can't figure out the equation. What is the algebra equation??!??!?

Denise S.

Yes but what would be the equation in a greater than or equal to sign
