A five game average of 148 
20090401 

From Shelly: (128 + 145 + 139 + 157 + x) divided by 5 = 148 matches the situation stated below:
A person bowled four games and scored 128, 145, 139, and 157. Find x, the score the person would need to have in the fifth game to average 148 for all five games.
How do I solve this and how am I supposed to add x like it says in the equation? Answered by Penny Nom.
