The amount that Tina and Ivan 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 Tina and Ivan had at first
= 4 u + 15 u
= 19 u
19 u = 228
1 u = 228 ÷ 19 = 12
Total amount that Tina and Ivan spent
= 1 u + 12 u
= 13 u
= 13 x 12
= $156
Answer(s): $156
