Can you please provide a step by step explanation to the question below. Thank You.

Project cost = $950,000

Project life = five years

Projected number of units sold per year = 10,000

Projected price per unit = $200

Projected variable cost per unit = 150

Fixed costs per year = $150,000

Required rate of return = 15%

Marginal tax rate = 35%

Assume straight-line depreciation to zero over five years, and ignore the half-year rule for accounting for depreciation.

Calculate the Degree of Operating Leverage (DOL) at the cash break-even, accounting break-even, and financial break-even sales quantities.
