I'm stuck with profit, help please!

I'm stuck with profit, help please!?
Here's a profit question I'm stuck with and can't figure out:
Ms Ward sells tights. Her cost of producing the tights are 50p and her fixed costs are £340 per week.
She sells each pair of tights for £3 and sells 450 a week.

How much profit did Ms Ward make in a week?

How much profit would Ms Ward make in a year.

This is just for once if I need help with my homework or maybe later could you answer these please in full detail and how could I solve this question, thanks! :)
