Best ResponseYou've already chosen the best response.1Let the number of correctly answered questions be \(x\). Then the number of incorrectly answered questions is \(20 x\). The number of points you get on this test is given by \(5x 2(20  x)\). Can you solve the inequality \(5x  2(20  x) > 0\)?

Best ResponseYou've already chosen the best response.1\(7x  40 > 0\). Now what are the values for \(x\)? When you get that, find the values for \(20  x\). You'd get your answer
