I need help understanding how to answer this question.

A firm make and sells surfboard using revolutionary manufacturing processes and materials. The firm sells its surfboard for $110 to its distributiors. The surfboards require $30 of foam and fiberglass and 1.0 direct labor hours and annual fixed cost of $475000. The firm compensates its manufacturing employees at the rate of $25 per. The firm also applies variable manufacturing overhead at the rate of 60% of direct labor dollars. If the firm increases the quality of its direct materials, it will experince of following new production cost:

• $45 direct materials
• 80% of the original lablor hours
• $50,000 more fixed cost
• Applies overhead rate of 50% of the direct labor dollars

What is the percentage change in sales dollars required to break even if the firm changes to the higher quality materials?
