The amount that Diana and Carl 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 Diana and Carl had at first
= 7 u + 20 u
= 27 u
27 u = 108
1 u = 108 ÷ 27 = 4
Total amount that Diana and Carl spent
= 2 u + 15 u
= 17 u
= 17 x 4
= $68
Answer(s): $68
