Total amount that Tim, Owen, Ian and Dylan spent
= 681 - 189
= $492
Total amount that Tim and Owen spent
= 8 u + 80
Total amount that Ian and Dylan spent
= 8 u + 80 + 92
= 8 u + 172
Total amount that Tim, Owen, Ian and Dylan spent
= 8 u + 80 + 8 u + 172
= 16 u + 252
16 u + 252 = 492
16 u = 492 - 252
16 u = 240
1 u = 240 ÷ 16 = 15
Total amount that Owen and Ian spent
= 5 u + 80
= 5 x 15 + 80
= 75 + 80
= $155
Total amount that Tim and Dylan spent
= 492 - 155
= $337
Answer(s): $337
