Lena had $12. She bought a pack of craft paper for $6 and a sharpener for $2. Which expression correctly shows the total money Lena has left?
A
$12 − (−$6) + (−$2)
B
$12 + (−$6) − (−$2)
C
$12 − (−$6) − (−$2)
D
$12 + (−$6) + (−$2)
The correct expression is C: $12 − (−$6) − (−$2)
To find the total amount of money Lena has left, we can subtract the cost of the pack of craft paper and the sharpener from her original amount of money.
Starting with $12, subtract $6 for the pack of craft paper:
$12 - $6 = $6
Then, subtract $2 for the sharpener:
$6 - $2 = $4
Therefore, the correct expression that shows the total money Lena has left is $12 - ($6) - ($2), which corresponds to option C.
To find the expression that correctly shows the total money Lena has left, we need to subtract the amounts she spent from the amount she initially had.
Lena initially had $12.
She spent $6 on a pack of craft paper.
She also spent $2 on a sharpener.
Therefore, the correct expression is:
$12 - $6 - $2
This simplifies to:
$12 - $8
Which further simplifies to:
$4
So, Lena has $4 left.
The correct expression that shows the total money Lena has left is:
C) $12 - (−$6) - (−$2)
