Answer:

6. Because to decrease = number × 100-% over 100(as a fraction)

which is =39.99 ×100-30% over 100

= 39.99 × 70/100

=27.993

After you take your answer from the decrease and subtract from the original price which is 39.99

39.99-27.993 *note the 39.99 has a zero at the end

the answer = 11.997 Rounded off it becomes 12
