A mathematician works for \(t\) hours per day and solves \(p\) problems per hour, where \(t\) and **\(p\)** are positive integers and \(1 . One day, the mathematician drinks some coffee and discovers that he can now solve \(3p+7\) problems per hour. In fact, he only works for \(t-4\) hours that day, but he still solves twice as many problems as he would in a normal day. How many problems does he solve the day he drinks coffee?
