The company Lucky Food produces and delivers meals in a small town. There are no other competitors, so Lucky Food is the only supplier in the local market. This is why the company can set every price for its meals, based on the analysis of demand schedule and its elasticity. The economists of Lucky Food have conducted market research and found out that the demand curve is linear for this market and can be shown as the following function: P = 25 - 0.0018Q. Lucky Food has fixed costs of running the business $20,000 USD and variable cost for each meal $5. What price and quantity on the demand line represent the break-even point?

QUESTION Firm ABC has based on the Double Declining Balance Method to compute the depreciation charges of the asset for each year (2nd year in 2022). The growth rate of the firm will continue by the rate forever. The firm should also invest an amount at a fixed investment rate of operating income each year and the firm's total debt amount covers only the bonds. The information about the firm and the market in year 2022 are given below. NOTE: PLEASE SHOW HOW YOU COMPUTE EACH OF THE ITEMS. Beta Coefficient Cost of Asset Dividend Payout Ratio EBITDA (Operating Cash Flow) Investment Rate Net Working Capital (2021) Net Working Capital (2022) ROE S&P500 Index Return Shipping and Installation Cost Tax Rate Total Firm Bonds Issued Total Firm Common Stocks Issued Treasury-Bill Rate Useful Life of the Asset : 2 : $370.000 : 30% : $1.500.000 : 15% : $120.000 : $150.000 : 20% : 12% : $30.000 : 25% : 6000 bonds : 15000 shares : 2% : 5 years b) Compute the value of the Firm's equity amount and debt amount in year 2022.
