Answer:
$30
Explanation:
To calculate the first discount, which is 10%, we need to multiply the original price of the camera by 10% or 0.1.
So the amount of discount Mia receives on the $300 camera would be:
Discount = 10% of $300 = 0.1 x $300 = $30
Therefore, Mia would receive a $30 discount on the camera during the first discount.
