Shaun and trudy are selling raffle tickets. so far, shaun has sold x tickets. trudy has sold 3 more tickets than half the number of tickets that shaun sold. which expression represents the number of raffle tickets that shaun and trudy have sold altogether?

Think about this logically. We know that Shaun= x, and that Trudy is that x with changes made to it. When we read that "Trudy has sold 3 more tickets," we make the expression "3 + x." When we read "than half the number of tickets that Shaun sold, the x becomes (1/2)x. So the expression for Trudy would be 3 + (1/2)x. When we combine this expression with Shaun's expression to find the number of raffle tickets sold together, we get x + 3 + (1/2)x. Simplified, this could also be (3/2)x + 3.
