Total amount that Paul, Perry, Elijah and Jeremy spent
= 535 - 132
= $403
Total amount that Paul and Perry spent
= 7 u + 60
Total amount that Elijah and Jeremy spent
= 7 u + 60 + -109
= 7 u + -49
Total amount that Paul, Perry, Elijah and Jeremy spent
= 7 u + 60 + 7 u + -49
= 14 u + 11
14 u + 11 = 403
14 u = 403 - 11
14 u = 392
1 u = 392 ÷ 14 = 28
Total amount that Perry and Elijah spent
= 5 u + 60
= 5 x 28 + 60
= 140 + 60
= $200
Total amount that Paul and Jeremy spent
= 403 - 200
= $203
Answer(s): $203
