Simone saved $90.25 and Dan saved $24.90
Step-by-step explanation:
Let,
Amount saved by Simone = x
Amount saved by Dan = y
Amount saved by Carly = z
Simone saved $65.35 more than her brother Dan
x = y + 65.35 Eqn 1
and $37.50 less than her sister Carly.
x = z - 37.50 Eqn 2
Carly saved $127.75
z = 127.75 Eqn 3
Putting value of z from Eqn 3 in Eqn 2
[tex]x = 127.75-37.50\\x=90.25[/tex]
Putting x=90.25 in Eqn 1
[tex]90.25=y+65.35\\90.25-65.35=y\\24.90=y\\y=24.90[/tex]
Simone saved $90.25 and Dan saved $24.90
