1. 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 don't understand how to graph!!
Let x = the amount that Seini earned Then x + 25 = the amount that Gavin The amount Gavin earned would also = 425 - x (your directions asked you to have 2 equations.) Together they earned 425: x + (x + 25) = 425 2x + 25 = 425 2x = 400 Now divide both sides by 2 to find x.
