Help me solve the following questions

NUMBER FOUR 1. Thomas Vila has budgeted that output and sales of his single product will be 100,000 units in the coming year. At this level of activity, his unit variable costs are budgeted at Sh.50 and his unit fixed costs at Sh.25. His sales manager estimates that the demand for the product would increases by 1000 units for every decreased of Sh.1 in unit selling price (and vice versa) and that at a unit selling price of Sh.200 demand would be nil. Information about two price increases has just been received from suppliers: one is for materials (which are included in Thomas Vila( variable costs) and one is for fuel (which included in his fixed costs). Their effect will be to increase both the variable and fixed costs by 20% each over the budgeted figures. Thomas Vila aims at maximizing profits from his business. Required: a. Calculate before the cost increases the budgeted contribution and profit at the budgeted levels of 100,000 units. (3 marks) b. Calculate the level of sales at which profits would be maximized and the amounts of these maximum profits before the cost increases. (4 marks) c. Show whether and by how much Thomas Vila should adjust his selling price in respect to increases in: . Fuel costs. (2 marks) . Material costs. (2 marks) 2.

(5 marks) ii Should earning of foreign exchange be a factor in a firm's pricing policy.
