Grange Manufacturing Company had net income of $300,000 in 2017 when the selling price per unit was $200 and data for variable and fixed costs were as follows:

Cost Schedule:
Variable Costs:	Direct Material	$28
	Direct Labour	$35
	Variable Manufacturing Overhead	$17
		$80
Fixed Costs:	Manufacturing Overhead	$225,000
	Advertising	45,000
	Administrative	150,000
		$420,000

i) Compute the number of units sold in 2017, using the equation method.

iv) Calculate the margin of safety in number of units and sales dollars.

v) Using the sales units calculated in (i), construct a breakeven chart for Grange Manufacturing Company, clearly showing the breakeven point and the margin of safety in units and dollars and the region representing profits and losses. [Use a scale of 2 cm to represent 1,000 units on the x-axis and 2cm to represent $200,000 on the y-axis].

vi) The president of Grange Manufacturing is under pressure from stockholders to increase operating income by 8% in 2018. Management expects per unit data and total fixed costs to remain the same in 2018. Compute the number of units that must be sold in 2018 to reach the shareholders desired profit level. Is this a realistic goal?

vii) Assume that Grange Manufacturing sells the same number of units in 2018 as it did in 2017. Assuming unit variable costs and total fixed costs remain unchanged, what would the selling price have to be in order to reach the stockholders desired profit level?
