The number of seconds in 7 days is $7\times24\times60\times60=604800$
The total cost is then $16.07\times604800= 9719136$
In scientific notation we have one digit in front of the decimal place and multiply it by 10 to the power of something, so the answer in scientific notation would be
$9.719136\times 10^6$ or sometimes $9.719136{\ } E6$. You can round it to as many decimal places as you like.
