Answer:
It increases by 50 units.
Explanation:
Current break even point = 
Here, fixed cost = $4,500
Contribution per unit = Selling price - Variable Cost = $20 - $10 = $10
Current break even point = 
If variable cost increase by 10% then revised variable cost = $10 + 10% = $11
Contribution per unit = $20 - $11 = $9 per unit
Break even sales in units = 
Difference in original and revised break even = Revised - Original = 500 - 450 units = 50 units,
Thus original break even increases by 50 units, = 50/450 = 11.11% increase.
Final Answer

D. $ 367.500
Explanation:
We have to first compute the total direct labor cost. This is done by multiplying the estimated direct labor hours with the hourly rate.
Total Direct Labour costs $ 17.50 per hour * 15,000 hours = $ 262,500
Estimated manufacturing overhead per the data in the question is 140 % of Direct labor cost,
Estimated manufacturing overhead is $ 262,500 * 140 % = $ 367,500
