The amount that Hilda and Peter 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 Hilda and Peter had at first
= 7 u + 20 u
= 27 u
27 u = 54
1 u = 54 ÷ 27 = 2
Total amount that Hilda and Peter spent
= 3 u + 16 u
= 19 u
= 19 x 2
= $38
Answer(s): $38
