Is my answer correct?

[Guest]

Can you please let me know if my answer is right or wrong?

Here is the question:

The main ingredient in a certain prescription drug capsule costs $500.00 per kilogram. If each capsule contains 600 mg, what is the cost of the ingredient in a capsule if 1kilogram=10^6milligrams?

My answer: $.30

Thank you!

I like it. Why are you questioning your result?

'cause sometimes I get simple questions wrong even though I'm sure I'm doing it right. This happens to me aaaaaaaaaaalllllll the time, not sometimes :?

No worries. It happens to everyone. Just keep trying. Maybe slow down a bit. Being more careful helps, but it isn't perfect. Progress based on effective practice make confidence grow.
