Total amount that Ethan, Henry, Lee and Billy spent
= 892 - 139
= $753
Total amount that Ethan and Henry spent
= 8 u + 60
Total amount that Lee and Billy spent
= 8 u + 60 + 313
= 8 u + 373
Total amount that Ethan, Henry, Lee and Billy spent
= 8 u + 60 + 8 u + 373
= 16 u + 433
16 u + 433 = 753
16 u = 753 - 433
16 u = 320
1 u = 320 ÷ 16 = 20
Total amount that Henry and Lee spent
= 5 u + 60
= 5 x 20 + 60
= 100 + 60
= $160
Total amount that Ethan and Billy spent
= 753 - 160
= $593
Answer(s): $593
