Answer
Find out the what is the clearance price of a manatee.
To prove
As given
The gift shop at manatee mall was having a clearance sale.
Everything was marked down 30%.
The original price of a manatee hat was $12.
30 % is written in the decimal form.

= 0.30
30% of the original price of a manatee = 0.30 × 12
= $ 3.6

= 12 - 3.6
= $ 8.4
Therefore the clearance price be $8.4 .
