To determine whether the Mallory’s solution is a
Answer to Problem 73PPE
Mallory’s reasoning is not correct.
Explanation of Solution
Given: Mallory says that she solves a inequality a + 3.2
Calculation:
No, Mallory’s reasoning is not correct because the solution of the given inequality may be in fraction/decimal on the number line. And we can not put every real number in the given inequality in order to find the solution. Even in this case, Mallory has just substituted integer values in the equation.
That is why, substituting values in the inequality does not guarantee that the solution is correct.
