The amount that Tiffany and Ben each had in the end is the same. Make the amount that each had in the end the same. LCM of 5 and 1 is 5.
Total amount that Tiffany and Ben had at first
= 8 u + 20 u
= 28 u
28 u = 84
1 u = 84 ÷ 28 = 3
Total amount that Tiffany and Ben spent
= 3 u + 15 u
= 18 u
= 18 x 3
= $54
Answer(s): $54
