Answer:
operating income will increase by $81,137.10 or 12.09%
Explanation:
we must first determine the old contribution margin of the sprinklers:
total variable costs = $6,863,512 + $2,651,657 = $9,515,169
total units sold = 491,740
variable cost per unit = $9,515,169 / 491,740 = $19.35
selling price per unit = $26.50
old contribution margin = $26.50 - $19.35 = $7.15
the new contribution margin per unit:
selling price = $26.70
variable cost per unit = $20.05
new contribution margin = $6.65
increase in units sold = 491,740 x 10% = 49,174 units
the impact of new product:
before, the company's total contribution margin was 491,740 x $7.15 = $3,515,941
operating income = $3,515,941 - $2,050,140 - $794,950 = $670,851
the new total contribution margin = 540,914 x $6.65 = $3,597,078.10
new operating income = $3,597,078.10 - $2,050,140 - $794,950 = $751,988.10
change in operating income = $751,988.10 - $670,851 = $81,137.10 or 12.09% increase
