The three girls gave equal amount of money to buy the souvenir. Make the amount that each spent the same. LCM of 1, 2 and 3 is 6.
Total amount that three girls had at first
= 24 u + 9 u + 8 u
= 41 u
41 u = 410
1 u = 410 ÷ 41 = 10
Cost of the souvenir
= 3 x 6 u
= 18 u
= 18 x 10
= $180
Answer(s): $180
