the average score is what you get while dividing the total scores in all the games divided by the total number of games played. take n as the additional number of games played and form the equation for the average

[(3)(120) + x(145)] / (x + 3) = 130 Solve for "x". "x" will be the number of additional games and "x + 3" is the total games. (3)(120) is 360 and is not necessarily indicative of having bowled 3 games at 120 each but morese shows that 360 is the total score before bowling more games.
