Jim: $16
Carmen: $9
Tom: $48

Explanation:

Let he amount of what Jim has be color(green)x

Carmen has 7 less than Jim so he has color(green)xcolor(red)(-7)

Tom has 3 times what Jim has so he has color(blue)3color(green)x

The total is 73 so,

x+(x-7)+3x=73

x+x-7+3x=73

Add like terms (x terms together)

5x-7=73

Add 7 to both sides

5xcancel(-7+7)=73+7

5x=80

Divide both sides by 5

x=16,

Now Jim has x so he has color(magenta)16

Carmen has 7 less than Jim so he has 16-7 which is color(magenta)9

Tom has 3 times Jim so he has 3(16) which is color(magenta)48.

To check your answer add those values together, they must sum up to 73

color(magenta)48+color(magenta)9+color(magenta)16=73, so the answer is correct
