Question

Rachel, Lamar, and Kareem sent a total of 101

 text messages during the weekend. Kareem sent 3

 times as many messages as Rachel. Lamar sent 6

 more messages than Rachel. How many messages did they each send?

Answer 1

r+L +k = 101

k=3r

L=6+r

r + 6+r + 3r = 101

5r = 101-6

r = 95/5 = 19 for rachel

k = 3(19) = 57 for kareem

L = 6+19 = 24 for Lamar
