I am traveling to Europe. New airline laws require only a maximum of 100 ml each fluid/gel medications to be carried on board. The several tubes of medication I recently got from my pharmacist are labeled either 15 grams or 30 grams, not in ml's. Since USA is WAY, WAY behind of using the metric system consistently, I have no idea if the 15 gram or the 30 gram tubes exceed the 100 mililiters limit. Can anyone help me? Thanks :)

I got 9.9 x 10 ^18.
However the products is where I differ from the answer.
4.5 x 10 ^7 x 2.2 x 10^11.
How were 7 and 11 arrived at? 7 + 11 = 18. And there are only 16 zero's so can someone please explain why it wouldn't be to the power of 6 and 10?

The weekly salary of an employee is $150 plus a 6% commission on total sales. The employee needs a minimum salary of $650 per week. How much must be sold to produce this salary?
My answer: $150.00 + 6% commision of sales
6% of 100 is $6.00
6% of 1000 is $60.00
$60.00 x 9 = 540 for a weekly salary of
$540 + $150 = $690.00 per week
Also
$60.00 x 8 = $480 for a weekly salary of
$480 + $150 = $630.00 per week
Total sales must be between $8,000 - $9,000 per week.
To be exact I think it would be Around $8,300.00
