There have been 7 more orders for Pepsi than for Mountain Dew.

Explanation:

We know that there have been 23 orders for Pepsi and 15 orders for Mountain Dew. To solve, we need to put this into an algebraic expression. The question asks how many more orders for Pepsi have there been, so all we have to do is subtract the number of Mountain Dew orders from the number of Pepsi orders. Our expression looks like this:
