answer 5-7 show formula and work please

Here are the assumptions: Sales price per unit = $ 14.31 per unit Total Fixed costs = 1,052,800 Variable cost per unit = $8.33 per unit Determine the following, showing both the formulas and calculations 1. Contribution margin per unit 2. Break-even point in units 3. Sales volume needed to reach a profit of $750,000 4. Now, apply the following INDEPENDENT changes and determine the impact on profitability (using sales units you calculated in 3 above) o Increase in sales price by 5% o Decrease in variable cost to $7.45 per unit o Change ibixed costs to 900,000 5. Create a Cost-Volume-Profit Graph for your last scenario above (fixed costs = $900,000) Be certain to include fixed, variable, break-even point and sales volume and translate your results. 6. If in this scenario where fixed costs = $900,000. your budgeted sales are 230K units, calculate your margin of safety? 7. Finally, prepare a sensitivity analysis, like the one shown in Exhibit 3.3 for our company, using the following what if scenarios, to calculate profitability (as in the Exhibit, incorporate these into one worksheet) Fixed costs in the range of $800K - 1,3M, in increments of 100K Variable costs in the range of $7.10 cost per unit, in $.50 increments Sales volume in units in the range of 150K - 500K units in increments of 50K units
