Question 312593: Please help me solve this finance: Ben, Jim, Alice, Erin, and Rick are friends. Ben is 20 years old, Jim is 17 years old, Alice is 21 years old, and Erin is 19 years old. The average age of the 5 friends is 20. How old is Rick? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! The average age of 5 = 20. The total of their ages =100
..
The total age of Ben, Jim, Alice, Erin,= 20+17+21+19=77
The difference = 33
So Ricks age = 33 years
