The amount that Sabrina and Julian each had in the end is the same. Make the amount that each had in the end the same. LCM of 3 and 1 is 3.
Total amount that Sabrina and Julian had at first
= 5 u + 12 u
= 17 u
17 u = 51
1 u = 51 ÷ 17 = 3
Total amount that Sabrina and Julian spent
= 2 u + 9 u
= 11 u
= 11 x 3
= $33
Answer(s): $33
