are both of these a compound or simple sentences I need to have these as a model for the other one's.

Question

1. Her mother went to trade show, but doreen stayed home.

2. Wang and his brother looked at the problem and spotted the solution.

i think:
1. compound because "Her Mother went to the trade show. Doreen stayed home" makes sense
but
2. simple because "Wang and his brother looked at the problem. Spotted the solution" doesn't work.

Julie is correct.

1. compound
2. simple (with compound subject and compound verb)

=)

What is the compound verb-
Janet has packed a lunch and will spend the day at the beach.
