Q. The mean-end analysis process centers around the detection of differences between the Current state' and goal state Once such a difference is isolated, an operator that can reduce the difference must be found. But perhaps that operator can not be applied to the current state. So a sub-problem of getting to a state in which it can be applied is set up. The kind of backward chaining in which operators are selected and then sub goals are set up to establish the precondition of operators is called

Q. "If my computations are correct and I pay the electric bill, then I will run out of money. If I don't pay the electric bill the power will be turned off. Therefore, if I don't run out of money and the power is still on then my computations are incorrect."
Convert this argument into logical notations using the variables c, b, r, p for propositions of computations, electric bills, out of money and the power respectively. (Where  ¬ means NOT)
