Answer:
Step-by-step explanation:
(146 + 187 + x)/3 = 160 Multiply both sides by 3
3(146 + 187 + x)/3 = 160*3
146 + 187 + x = 480 Combine the terms on the left
333 + x = 480 Subtract 333 from both sides.
333 - 333 + x = 480 - 333
x = 147
If he gets at least 147, his average of 160. Any score above that, will put his average above 160.
187 was a monster score.
So the answer should read. Ben must bowl at least 147 in his third game in order to have an average of at least 160.
