Here’s my solution… using “models”. Somehow I feel I’m not doing the right thing. Hmm…
Let x be the money each of them spent.
J J J J <—x—>
E <— x—>
539 – x = 4(275 – x)
539 – x = 1100 – 4x
3x = 1100 – 539 = 561
X = 561/3 = $187 #

J -?—-u–u–u–u
E -?—-u–<-3u->
?= Spent
3u = 539-275 =264
u = 264/3 = 88
Therefore, Spent = 275 – 88 = $187
