CableVision has been approached by the City of Mirada to run its cable operations in 2016. After negotiating with key parties, CableVision has made the following agreements: It will offer Mirada residents a basic set of 25 cable television stations at a rate of $31.49 per month. CableVision will pay the city $1,300,000 per year plus $3.75 per cable subscriber per month to maintain the physical facilities. CableVision will actually pay another company a monthly fixed fee of $50,000 plus $8.75 per cable subscriber per month to broadcast the 25 channels. CableVision estimates that operating costs for billing, program news mailings, etc. will be $125,000 per month plus 8% of monthly revenue. CableVision has several questions about its monthly revenues, costs, and profits in 2016. 1. What is CableVision's estimated monthly operating income in 2016 if 18,000 residents subscribe? 2. How many monthly subscribers would be required for CableVision to break even in 2016? 3. How many monthly subscribers would be required for CableVision to earn $25,000 per month in 2016? 4. Assuming a tax rate of 35%, what must revenue be in order for CableVision to earn $25,000 per month in 2016?
