The total number of balls remains unchanged after Carl gives to Elijah.
Total number of balls
= 114 + 299
= 413
Total number of balls in the end
= 1 u + 1 u + 119
= 2 u + 119
2 u + 119 = 413
2 u = 413 - 119
2 u = 294
1 u = 294 ÷ 2 = 147
Number of balls that Carl must give to Elijah
= 147 - 114
= 33
Answer(s): 33
