I need help answering the following question:

management is considering using higher quality components that would increase the variable expense by $2 per unit. The marketing manager believes that the higher quality product would increase sales by 10% per month. Should higher quality components be used?

selling price $90 per unit/percent of sales 100%

Variable expenses-63 per unit/percent of sales 70%

Contribution margin-$27 per unit/percent of sales 30%

fixed expenses- $30,000 per month and the company is selling 2,000 units per month
