The amount that Min and Lee each had in the end is the same. Make the amount that each had in the end the same. LCM of 4 and 1 is 4.
Total amount that Min and Lee had at first
= 7 u + 24 u
= 31 u
31 u = 93
1 u = 93 ÷ 31 = 3
Total amount that Min and Lee spent
= 3 u + 20 u
= 23 u
= 23 x 3
= $69
Answer(s): $69
