The accommodative ability changes greatly because of age-related changes in the eye, including a decrease in the elasticity of the lens and the degeneration of the Zonular fibers and the ciliary muscles surrounding the lens.

The process of accommodation, or focusing on near objects, happened by a concerted action of the ciliary muscle on the zonule fibers which hold the lens in place. The ciliary muscle can be described as a ring of smooth muscle that, upon contraction, relaxes the tension on the zonular fibers and allows the lens to become more spherical.

A producer of felt-tip pens has received a forecast of demand of 31,000 pens for the coming month from its marketing department.
atroni [7]

Answer:

  • a. <em>Break-even quantity:</em> <u>28,000 pens</u>

  • b<em>. Price</em>: <u>$1.51 per pen</u>

Explanation:

1. Break-even quantity

<u>a) Revenue, R(x)</u>

The  monthly revenue is the product of the price by the number of units sold in the month.

Naming x the number of pens sold in the month:

  • R(x) = $1 × x = x

<u>b) Cost, C(x)</u>

<u />

The monthly cost is the sum of the fixed cost per month plus the variable costs:

  • C(x) = $21,000 + 0.25 × x = 21,000 + 0.25x

<u>c) Break-even</u>

Break-even is the point when the revenue and the total costs are equal, this is, when the profit is zero. Write the equation and solve:

  • x = 21,000 + 0.25x
  • x - 0.25x = 21,000
  • 0.75x = 21,000
  • x = 21,000 / 0.75
  • x = 28,000

Hence, the break-even quantity is 28,000 pens.

2. Price pens must be sold to obtain a monthly profit of $18,000

Profit = Revenue - Total cost

  • P(x) = R(x) - C(x)

  • P(x) = x.p - [ 0.25x + 21,000]

Where p is the price.

  • P(x) = x.p - 0.25x - 21,000

Substitute the quantity demanded, x, with 31,000, and the profit, P(x) with 18,000:

  • 18,000 = 31,000p - 0.25(31,000) - 21,000

Solve for p and compute:

  • 31,000p = 18,000 + 7,750 + 21,000

  • 31,000 p = 46,750

  • p = 1.51

That is $1.51 per pen.

Which of the following is not a fee that contributes to the initial cost of leasing a car? a. First payment b. Final payment c.
Darya [45]

The final payment is <u><em>not </em></u>a fee that contributes to the original cost of leasing an automobile, option B is the correct answer.

<h3 /><h3>How is leasing charged?</h3>

The first payment is, predictably, the same as one month's rent.

A lender or lessor will impose an acquisition fee to offset the costs of establishing a loan or lease agreement.

A disposition fee, sometimes known as a turn-in fee, is a cost associated with returning a rented vehicle.

Therefore, final payment doesn't contribute to leasing a car.
