The amount that Joelle and Daniel 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 Joelle and Daniel had at first
= 7 u + 16 u
= 23 u
23 u = 115
1 u = 115 ÷ 23 = 5
Total amount that Joelle and Daniel spent
= 3 u + 12 u
= 15 u
= 15 x 5
= $75
Answer(s): $75
