Answer:
The amount that Stephen receives is [tex]\$147[/tex]
Step-by-step explanation:
Let
x-------> amount Richard receives
y------> amount Stephen receives
z------> amount Bridget receives
we know that
[tex]x+y+z=\$490[/tex] ------> equation A
[tex]x=2y[/tex] -----> equation B
[tex]y=3z[/tex]
[tex]z=y/3[/tex] ----> equation C
substitute equation B and equation C in equation A and solve for y
[tex](2y)+y+(y/3)=490[/tex]
[tex](10y/3)=490[/tex]
[tex]y=490*3/10=\$147[/tex]
