Answer:
Step-by-step explanation:
The average of 4 games was 160. The average consists of the sum of all the scores, divided by 4:
(Sum of Games)/4
Sum of 2 games is (155 + 169) = 324
Lets let the sum of the two unknown games be x.
(234 + x)/4 = 160
(234 + x) = 640
x = 316
x consists of 2 games, so their average is (316/2) = 158 per game for the other 2 games.
===============
Check:
(155+169+158+158)/4
(640/4) = 160 average for all games.
