asked • 07/07/22Nicole, Goran, and David sent a total of 85 text messages during the weekend. Nicole sent 5 more messages than Goran. David sent 3 times as many messages as Goran. How many messages did they each send?
Raymond B. answered • 07/07/22
Math, microeconomics or criminal justice
N+G+D = 85
D=3G
N=5+G
substitute last two equations into the 1st equation to get:
5+G +G + 3G = 85
5G =85-5= 80
G =80/5 = 16 messages sent by Goran
N=16+5 = 21 messages sent by Nicole
D =3(16) =48 messages sent by David
