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

$x = 127.75-37.50\\x=90.25$

Putting x=90.25 in Eqn 1

$90.25=y+65.35\\90.25-65.35=y\\24.90=y\\y=24.90$

Simone saved $90.25 and Dan saved $24.90
