Final answer:
Kim made 122 questions and Kiley made 42 questions.
Step-by-step explanation:
Let's assume the number of questions Kim made is represented by 'x' and the number of questions Kiley made is represented by 'y'.
According to the given information, Kim made 4 less than three times the number of questions Kiley made. So we can write the equation: x = 3y - 4.
Together, they made 164 questions, so we can write the equation: x + y = 164.
Using the first equation, substitute x with 3y - 4 in the second equation: 3y - 4 + y = 164. Simplifying, we get 4y - 4 = 164. Solving for y, we find y = 42.
Substituting y = 42 back into the equation x = 3y - 4, we find x = 122. Therefore, Kim made 122 questions and Kiley made 42 questions.
