Answer:
- Raphael: 88
- Goran: 22
- Lucy: 30
Explanation:
Let g represent the number of messages Goran sent. Then 4g is the number Rafael sent, and g+8 is the number Lucy sent. Their total is ...
(g+8) +g +4g = 140
6g = 132
g = 22
g+8 = 30
4g = 88
Lucy sent 30 messages; Goran sent 22; and Rafael sent 88.
