Gavin and Seiji both worked hard over
the summer. Together, they earned a total of $425. Gavin earned $25
more than Seiji. How much did each of them earn?
(a)
Write a system of two equations with two variables to model this problem.
(b)
Use substitution or the elimination method to solve the system.
(c)
Graph both equations.
(d)
Answer the question.
I already did all except C. I need help for C! Can somebody explain this to me please?
(lol it rhymes.)
And heres my work.
G=Gavin, S= Seiji
Gavin=Seiji+25;g+s=425
g+s=425
s+25+s=425
2s+25=425
2s+25+−25=425+−25
2s=400
2s/2=400/2
s=200
g=225
