The amount that Kylie and Vaidev 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 Kylie and Vaidev had at first
= 7 u + 24 u
= 31 u
31 u = 155
1 u = 155 ÷ 31 = 5
Total amount that Kylie and Vaidev spent
= 3 u + 20 u
= 23 u
= 23 x 5
= $115
Answer(s): $115
