relevant cost

Sir, I got nothing left other than texting you full question.... i desperately need help on finding the answer of B and C thank you in advance ? Mrs Glam wants to expand her clothes shop. Mrs Glam has commissioned a market research company at a cost of $3,000 to research her options for her. The company have offered two options: Option 1 Remain in her the current premises and undertake an advertising campaign at a cost of $2,000 to increase the profile of the shop in the area. It is estimated that revenue will increase by 10% from its current level of $50,000 per year. The contribution earned on revenue is 30%. Option 2 Move the shop to a more central location and undertake an advertising campaign to both increase the profile and the move to new premises. This more extensive campaign would cost $4,000 but revenue would be expected to increase by 18% from its current level. The level of contribution earned on revenue is not expected to change. There would be further costs involved in moving location which have been estimated: ? Moving costs are estimated to be $1,500. This includes the cost of refitting the shop, and would be payable immediately ? New shop fittings will be required costing $2,500. These will be depreciated on a straight line basis. ? Rates of $4,000 will be payable yearly in advance. This cost is 15% higher than Mrs Glam currently pays, due to the location. Other information ? Mrs Glam uses a cost of capital of 10% ? The expansion is to have a life of 4 years. Required: (b) Calculate the present value of the INCREMENTAL contribution cash flow that will arise if option 2 is compared to option 1. (c) Calculate the present value of the cash flows relating to the INCREMENTAL rates that will arise if option 2 is compared to option 1
