Since Karl earns $4 per hour and works 2 more hours than Missy, who earns $5 per hour, let's denote the number of hours Missy works as x. Therefore, Missy earns 5x dollars. Karl works x + 2 hours, earning 4(x + 2) dollars. Setting these equal to each other because they earn the same amount gives us 5x = 4(x + 2). Solving for x gives x = 8, meaning Karl works x + 2 = 10 hours.
