Finger [1]

Answer:

$1,818,181.81

Explanation:

Data provided:

Amount that will be provided a year = $50,000

Expected rate of return = 2.75%

Now,

The Present value of perpetuity is given as:

Present value of perpetuity = \frac{\textup{Annual return}}{\textup{Expected rate of return}}

on substituting the respective values, we get

Present value of perpetuity = \frac{\textup{50,000}}{\textup{0.0275}}

or

Present value of perpetuity = $1,818,181.81

Hence,

The amount that must be deposited today to fund this gift is $1,818,181.81

The Porch Cushion Company manufactures foam cushions. The number of cushions to be produced in the upcoming three months follows
yKpoI14uk [10]

Answer: 25,200 pounds

Explanation:

Your question is incomplete as it lacked the first part. I attached a completion that I found.

The company has a policy that the ending inventory of foam each month must be equal to 30% of the following month's expected production needs.

This means that in August, the Opening inventory will be 30% of what was is needed in August and the Closing Inventory will be 30% of what is needed in September.

Remember that each cushion requires 2 pounds of foam as stuffing.

Pounds required in August

= 12,000 cushions * 2

= 24,000 pounds

Opening Stock

= 30% * (12,000 * 2)

= 7,200 pounds

Closing stock

= 30% * ( 14,000 * 2)

= 8,400 pounds.

Foam needed to be purchased in August = Pounds required tonbe produced + Closing Stock - Opening Stock

= 24,000 + 8,400 - 7,200

= 25,200

25,200 pounds of foam are what The Porch Cushion Company needs to purchase in August.
