1x4 =
4 u |

Comparing Andy
and Xavier in the end |

The amount that Xavier had in the end is the same. Make the amount that Xavier had in the end the same. LCM of 1 and 4 is 4.
Total amount that Xavier and Andy had at first
= 3 u + 24 u
= 27 u
27 u = 405
1 u = 405 ÷ 27 = 15
Amount that Xavier had at first
= 24 u
= 24 x 15
= $360
Answer(s): $360
