Why 1805 plus 260? I thought the total for 3 of them were 1805?
Yeah, good question, we don't know Robby has how many, so we add 260 to Robby become 3u. (Robby + 260 = 3u) Robby and Paul same = 3u now
Paul = 3u
Jack = 1u
Robby + Paul + Jack = 1805
(Robby + 260) + 3u + 1u = 1805 + 260
(3u) + 3u + 1u = 2065
Paul = 3u
Jack = 1u
Robby + Paul + Jack = 1805
(Robby + 260) + 3u + 1u = 1805 + 260
(3u) + 3u + 1u = 2065
Thank you so much. Have a clearer understanding now.
