Your task is to develop an email extractor algorithm (flowchart AND pseudocode) and then write a python modular program that implements the algorithm. The python program should read text from input file and extracts all email addresses within the text. An email address has the following format: email_id@domain_name The email_id is the part preceding the @ symbol and it may contain only letters (a-z, A-Z), digits (0-9), and any of the symbols: ., $, _, or -. Note no other character is allowed in the email_id. The next part is the domain_name which is composed of domain.ext(.ext) * where domain_name may contain only letters (a-z, A-Z), digits (0-9), and only the two symbols . or -. Note that domain_name may allow zero or more extra .ext parts (as indicated by *) but it must at least contain one .ext part. The table below give some examples of valid emails:

The answer is a) 12.48% but how? Simple Tech Inc is an Australian company operating in a pure imputation tax system. It is currently financed entirely (100%) by equity and has a beta of 0.8. After examining its capital structure, Simple Tech finds that the optimal capital structure can be achieved at D/E ratio of 0.4. The before-tax cost of debt capital for Simple Tech at the optimal capital structure is 10% p.a. The risk-free rate and market risk premium are 5% p.a. and 7% p.a., respectively. If the statutory corporate tax rate is 30%, which of the following is closest to the cost of equity at the optimal capital structure (using the approach covered in the lecture)? a. 12.84% p.a. b. 12.17% p.a. c. 12.03% p.a. d. 11.69% p.a. e. 10.60% p.a.
