The amount that Irene and Lee 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 Irene and Lee had at first
= 4 u + 15 u
= 19 u
19 u = 152
1 u = 152 ÷ 19 = 8
Total amount that Irene and Lee spent
= 1 u + 12 u
= 13 u
= 13 x 8
= $104
Answer(s): $104
