Mike has $40, which is $6 more than twice the amount of money that Karly has. How much money does Karly have?

Question

the answer choices:

A. $14

B. $17

C. $23

D. $74

Answer 1

First, we need to set up our equation. Let's start by using "x" to represent the amount of money that Karly has.

Mike has $40, and we know that Karly's total amount of money needs to be doubled (2x) and added to 6 in order to reach Mike's total amount of money ($40).

Therefore, we know:

40= 2x+6

-6 = -6

34= 2x

34/2= 2x/2

17= x

Since Karly's total amount equals x, we know that Karly has a total of $17. Therefore B. $17 is the correct answer.
