The amount that Sabrina and Dylan each had in the end is the same. Make the amount that each had in the end the same. LCM of 3 and 1 is 3.
Total amount that Sabrina and Dylan had at first
= 4 u + 9 u
= 13 u
13 u = 130
1 u = 130 ÷ 13 = 10
Total amount that Sabrina and Dylan spent
= 1 u + 6 u
= 7 u
= 7 x 10
= $70
Answer(s): $70
