In a learning experiment, a subject is first given x minutes to examine a list of facts. The fact sheet is then taken away and the subject is allowed y minutes to prepare mentally for examination based on the fact sheet. Suppose it is found that the score achieved by a particular subject is related to x and y by the formula S(x,y) = x2 + 5xy + 15x – y2 + 3y + 25. i. What will be the subject’s score if he takes the test ‘cold’ (i.e. No study nor Contemplation)?
