Answer:
Assuming there is no change in price or the quantity demanded, if Westerlund wants to increase her advertising expenses to a total of $1,000 (a $500 increase), this would cause total costs to <u>INCREASE</u> and the break-even quantity to <u>INCREASE</u>.
Explanation:
total variable costs per unit = $5 (glass) + $2 (mating) + $13 (frame) + $30 (labor) = $50 per frame
total fixed costs = $1,000 (rent) + $200 (utilities) + $500 (advertising) + $3,500 (manager's salary) = $5,200
sales price = $120 per frame
contribution margin = $120 - $50 = $70 per frame
current break even point = $5,200 / $70 = 74.29 ≈ 75 frames per month
if fixed costs increase by $500 (total fixed costs = $5,200 + $500 = $5,700)
the new break even point = $5,700 / $70 = 81.43 ≈ 82 frames per month
