The amount that Raeann and Lee 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 Raeann and Lee had at first
= 7 u + 8 u
= 15 u
15 u = 135
1 u = 135 ÷ 15 = 9
Total amount that Raeann and Lee spent
= 3 u + 4 u
= 7 u
= 7 x 9
= $63
Answer(s): $63
