To find the total money Lena has left, we need to subtract the amount she spent from the initial amount she had.
First, Lena spent $6 on a pack of craft paper. We can represent this as -$6.
Then, she spent $2 on a sharpener. This can be represented as -$2.
Finally, we subtract the total amount Lena spent from her initial amount of $12:
$12 - (-$6) - (-$2)
We can simplify this expression:
$12 + $6 + $2
So the correct expression to show the total money Lena has left is:
C) $12 - (-$6) - (-$2)
To find the expression that correctly shows the total money Lena has left, we need to subtract the amounts she spent from the initial amount she had.
Lena had $12, and she spent $6 on craft paper and $2 on a sharpener.
We can represent the money spent as negative amounts since they are subtracted from the initial amount. So, the expression that represents the total money Lena has left is:
$12 - ($6) - ($2)
Now, let's simplify this expression:
$12 - $6 - $2
Subtracting the amounts, we get:
$4
Therefore, the correct expression that shows the total money Lena has left is:
$12 - ($6) - ($2) which is equivalent to C: $12 - (−$6) - (−$2)
