To solve, we add the 4 numbers (including the one unknown) and divide that total by 4, and this equals the desired overall average of 154.
x= score needed on 4th game
(149 + 162 + 152 + x)/4= 154
add in parentheses
(463 + x)/4= 154
multiply both sides by 4; 4 "cancels out" on the left side
463 + x= 616
subtract 463 from both sides
x= 153
ANSWER: 153 is the score needed on the 4th game to reach the desired overall average of 154.
Hope this helps! :)
