Mean age = 1271.27
Step-by-step explanation:
No of children = 77
The age at which children first began to combine words = 16.51 months
Mean age = No of children × age at which children first began to combine words
= 77 × 16.51
= 1271.27
Mean age = 1271.27

Answer: $611</h3>
Work Shown:
30% of 470 = 0.30*470 = 141
The value goes up by $141, so the answer would be 470+141 = $611
A slight shortcut would be to say
1.30*470 = 611
This works because 1.30 = 1 + 0.30 = 100% + 30%
