North safety products manufactures butyl gloves that offer permeation resistance to gas or water vapors for workers that use dan
never [62]

Company fixed cost = $10 million = $10,000,000

Variable cost per pair = $5

Company charges each pair = $15

Hence the company makes $10 profit per pair regardless the company fixed cost and only considering the variable cost.

Let subtract the variable cost per pair from the company charging each pair = 15 - 5 = $10

Thus the company now makes $10 per pair, and it has to sell 1,000,000 pairs of gloves to reach the break-even point. The break-even point refers to the point where total cost and revenue are equal.

<span>Thus for 1,000,000 pairs, the company total earning = 10 x 1,000,000 = $10,000,000 = $10 million  </span>

snow_tiger [21]

Answer:

45 mins

Step-by-step explanation:

The question is how much time should the painter spend on painting a doll for the costs to still be equal or lower to $24.50

We can make this equation, representing the raw materials + the painting job (at $18/h):

$11 + $18x = $24.50

18x = 13.50

x = 13.5 / 18 = 0.75

So, the painter should spend at most 3/4 of an hour (or 45 mins) painting a doll to keep the cost at or below $24.50 per doll.
