The amount that Kimberly and Pierre each had in the end is the same. Make the amount that each had in the end the same. LCM of 2 and 1 is 2.
Total amount that Kimberly and Pierre had at first
= 5 u + 12 u
= 17 u
17 u = 34
1 u = 34 ÷ 17 = 2
Total amount that Kimberly and Pierre spent
= 3 u + 10 u
= 13 u
= 13 x 2
= $26
Answer(s): $26
