Final answer:
Karly has $17. This was determined by setting up the equation 40 = 2K + 6 based on the information given, solving for K (Karly's amount), and finding that when Mike's $40 is $6 more than twice what Karly has, she must have $17.
Step-by-step explanation:
The student's question involves solving a simple algebraic equation to find out how much money Karly has. Mike has $40, which is $6 more than twice the amount of money Karly has. We can write this situation as an algebraic equation where K represents the amount of money Karly has:
40 = 2K + 6
To solve for K, we first subtract 6 from both sides of the equation:
40 - 6 = 2K + 6 - 6
34 = 2K
Next, we divide both sides by 2 to find the value of K:
34 / 2 = 2K / 2
17 = K
So, Karly has $17.
