Let us set up some variables:

  b: # of books

  m: # of magazines

Let us set up some equations based on the known facts:

  • Genesis bought a total of seven books --> b + m = 7
  • Genesis spent a total of $28.50 --> 5.5b + 3m = 28.5

Equations:

  • b + m = 7 -- equation 1
  • 5.5b + 3m = 28.5 -- equation 2

Start Solving:

   (Equation 1) * 3

    3b + 3m = 21 -- equation 3

   (Equation 2) - (Equation 3)

    2.5b = 7.5

    b = 3 -- equation 4

   (Equation 4) plug into (Equation 1)

  3 + m = 7

   m = 4

Solutions: Genesis bought 3 books and 4 magazines

Hope that helps!

General Forge and Foundry Company has a quick ratio of 2.00; $38,250 in cash; $21,250 in accounts receivable; some inventory; to
Vlada [557]

Answer:

The answer is General Forge and Foundry Company selling and replacing its inventory 2.55 times per year on average.

Explanation:

We have:

The company cost of good sold = Sales x 65% = 100,000 x 65% = $65,000

The company inventory = Total current asset - Cash - Account Receivable = 85,000 - 38,250 - 21,250 = $25,500

=> Inventory turn over ratio = Cost of good sold / Inventory = 65,000/25,500 = 2.55 times or the company is selling and replacing its inventory 2.55 times per year.

So, the answer is 2.55 times.

Giving the following information:

Bob makes his first $ 800 deposit into an IRA earning 7.4 % compounded annually on his 24th birthday and his last $ 800 deposit on his 39th birthday ​(16 equal deposits in​ all). With no additional​ deposits, the money in the IRA continues to earn 7.4 % interest compounded annually until Iob retirees on his 65th birthday.

First, 16 years:

FV= {A*[(1+i)^n-1]}/i

A= annual deposit

FV= {800*[(1.074^16)-1]}/0,074= $23,067.90

Next 25 years.

FV= PV*(1+i)^n

FV= 23,067.90*(1.074)^25= $137,440.62
