The amount that Emma and Sean 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 Emma and Sean had at first
= 7 u + 20 u
= 27 u
27 u = 108
1 u = 108 ÷ 27 = 4
Total amount that Emma and Sean spent
= 3 u + 16 u
= 19 u
= 19 x 4
= $76
Answer(s): $76
