You bowl 3 games and get an average score of 120. How many additional consecutive games with scores of 145 would you need to bring your average up to 130?
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.
