Answer:
To determine the net income under Alternative 2-Drive-Thru when sales units remain the same as last year, we would need the specific values for the sale price, variable cost, and any fixed costs associated with Alternative 2. Unfortunately, you mentioned using the same number of units sold as last year for Alternative 2 but did not provide the necessary information.
If you can provide the sale price, variable cost, and any fixed costs associated with Alternative 2, I can help you calculate the net income.
