Note that in the previous problem, \(x\) represented the number of weeks, \(y\) represented the amount of money, \(400 – 15x\) represented the amount of money he would have after \(x\) weeks. In order to determine whether the shading is correct, a point in the region needs to be selected to determine if it works in the inequality.
