Melissa scored w points in each game. She also got x bonus points in each game. How many points did she score in y games?
First, we need to find out how many points Melissa scored in each game. We know that she scored w points in each game, and she also got x bonus points in each game. This means that she must have scored w + x points in each game. 

Now, we need to find out how many points she scored in y games. To do this, we need to multiply the number of points she scored in each game by the number of games she played. We know that she scored w + x points in each game, and she played y games. This means that she must have scored (w + x)*y points in total. 

Therefore, the answer (symbolic expression) is: 

(w + x)*y
