Below are the questions for the assignment. I have reached out to the professor and have not heard back. I need help to solve these as well as how they would look in excel.

This is the article as well: https://aisel.aisnet.org/cgi/viewcontent.cgi?article=1066&context=jise

Questions:

Evaluate the situation, do you recommend that an additional register (handling both cash and credit/debit cards) be purchased? What about a card-only tablet for processing card transactions? Explain your reasons for these decisions.

Evaluate if the caf should charge a fee of $0.25 per transaction for credit card purchases under $1.25, considering the gain from fees, assuming a profit margin of 40% of total sales and an estimated 30% in lost sales (for items $1.25 or less). Is there any potential gain worth the possibility of loss of customers?

Assess the breakeven point. Considering only the $855 startup costs, the first week of sales (obtainable from the data), and assuming a 30% profit margin on sales, did the caf "break even" when it decided to hire previous employees in order to open one week earlier (five business days) in the semester? Show your calculations and assumptions.

Thank you!
