need to solve the following problem

Peggy-Sue's cookies are the best in the world, or so I hear.
She has been offered a job by Cookie Monster, Inc., to
come to work for them at $125,000 per year. Currently,
she is producing her own cookies, and she has revenues of
$260,000 per year. Her costs are $40,000 for labor,
$10,000 for rent, $35,000 for ingredients, and $5,000 for
utilities. She has $100,000 of her own money invested in
the operation, which, if she leaves, can be sold for
$40,000 that she can invest at 10 percent per year.

a. Calculate her accounting and economic profits.
b. Advise her as to what she should do.
