Answer:
$135
Explanation:
Assuming that the 70% discount was applied on the original price of $450,
you multiply 0.7 (70%) to 450 and subtract that value from the original price. Basically, you are left with 30% of the original price.
Imagine taking the full price of the camera and subtracting 70% off that original price.
450 - (0.7)(450) = $135
The price of the camera after the 70% off discount is $135.
