Urgent clarification needed for Consumer Arithmetic please! (1 Viewer)

I have a test tomorrow and I'm still confused about this.

Q: A and B buy a $1200 BBQ on a deferred payment plan, no deposit required. They pay nothing for 6 months and then they pay 18 monthly payments of $90. How much extra did A and B pay and what is the flat rate of interest charged?

How does one do the question when the IS deposit? Can someone show me the steps?
Thank you!

You sure you typed this up correctly? I dont see the difference between what A is doing and B is doing with regards to their payments for the BBQ
