I'm not sure about the "four problem solving steps", but here's howI'd do it, Let x = number of courses after their freshman year. Assumethat both girls take the same number of courses Credits for Kirsten: 43 + 5x Credits for Beth: 47 + 3x You want to know how many classes they need to take before theyboth have the same credits, so set the equations equal to eachother and solve for x: 43 + 5x = 47 + 3x 2x = 4 x = 2 So, after they both take 2 more courses, they'll have the samenumber of credits. How many credits is that? 43 + 5(2)= 53 Credits.
