Answer:
$72.00
Explanation:
Lets round $6.99 to $7.00. Now we have an easier number to work with.
To find the total price of 12 , we need to multiply $7.00 by 12.
⇒ $7.00 x 12 = $84.00
Since we added 1 cent to $6.99 and multiplied by 12, we need to sutract 1 times 12.
1 x 12 = 12
$84 - $12 = $72.00
