Answer: Jackson has $75
Step-by-step explanation:
Step 1
Let the amount of money Christabelle has = x
Let the amount of money Jackson has = 3x
and the amount of money Janessa has= 3x+ 263
Such that the total money they all have which = $438 be expressed as
Christabelle's money +Jackson's money + Janessa's money= $438
x+ 3x+ 3x+ 263 = 438
Step 2 ---Solving
x+ 3x+ 3x+ 263=438
7x= 438-263
7x=175
x =175/7
x=25
Therefore,
Christabelle = $25
Jackson = 3x= 3 x25 = $75
Janessa= 3x+ 263= $75+263=$338
