Answer:
(a)
system of equations are
[tex]s+k=425[/tex]
[tex]k-s=25[/tex]
(b)
Graph is attached
(c)
Sam earned =$200
Kevin earned =$225
Step-by-step explanation:
Let's assume
's' for the amount Sam earned
'k' for the amount Kevin earned
(a)
Together they earned a total of $425
so, we get
[tex]s+k=425[/tex]
Kevin earned $25 more than Sam
so, we get
[tex]k=s+25[/tex]
so, system of equations are
[tex]s+k=425[/tex]
[tex]k-s=25[/tex]
(b)
now, we can draw graph
(c)
intersection point will be our solution
and we got intersection point as
(200, 225)
so,
s=200
k=225
