15. Preliminary plans are underway for construction of a new stadium for a major league base ball team. City officials question
Arlecino [84]

Answer:

Ans.

a) The breakeven point for the number of luxury boxes in the new stadium is 30 units ($9,000,000 in sales)

b) My recomendation is to sell at 300k until the break even point is reached and after that you should consider incrementing the unit´s price.

c) If the price and the costs remain as they are, the profit would be  $3,000,000 with sales of $15,000,000.

Step-by-step explanation:

Hi, first let me show you what is the equation that we have to use in order to find the break even point (in units) or BEP.

BEP=\frac{Fixed Costs}{(Price-VarCost)} =\frac{4,500,000}{(300,000-150,000)} =30

So the break even point is 30 units, which is the same to say $9,000,000 in sales ($300,000 per unit * 30 Units).

The profit that you should anticipate, if all remains the  way it is:

Profit=(Price-VarCost)*Units-FixedCosts

Profit=(300,000-150,000)*50-4,500,000=3,000,000

Best of luck.

1/3(z+4)-6=2/3(5-z) solve for z and check solution
Marat540 [252]

Answer:

z = 8

Step-by-step explanation:

Solve for z:

(z + 4)/3 - 6 = (2 (5 - z))/3

Put each term in (z + 4)/3 - 6 over the common denominator 3: (z + 4)/3 - 6 = (z + 4)/3 - 18/3:

(z + 4)/3 - 18/3 = (2 (5 - z))/3

(z + 4)/3 - 18/3 = ((z + 4) - 18)/3:

(z - 18 + 4)/3 = (2 (5 - z))/3

Add like terms. 4 - 18 = -14:

(z - 14)/3 = (2 (5 - z))/3

Multiply both sides by 3:

(3 (z - 14))/3 = (3×2 (5 - z))/3

(3 (z - 14))/3 = 3/3×(z - 14) = z - 14:

z - 14 = (3×2 (5 - z))/3

(3×2 (5 - z))/3 = 3/3×2 (5 - z) = 2 (5 - z):

z - 14 = 2 (5 - z)

Expand out terms of the right hand side:

z - 14 = 10 - 2 z

Add 2 z to both sides:

2 z + z - 14 = (2 z - 2 z) + 10

2 z - 2 z = 0:

2 z + z - 14 = 10

z + 2 z = 3 z:

3 z - 14 = 10

Add 14 to both sides:

3 z + (14 - 14) = 14 + 10

14 - 14 = 0:

3 z = 10 + 14

10 + 14 = 24:

3 z = 24

Divide both sides of 3 z = 24 by 3:

(3 z)/3 = 24/3

3/3 = 1:

z = 24/3

The gcd of 24 and 3 is 3, so 24/3 = (3×8)/(3×1) = 3/3×8 = 8:

Answer:  z = 8

jill mowed lawns for 3 hours and earned $7.20 per hour.Then she washed windows for 4 hours and earned $6.75 per hour. what were
Aleksandr-060686 [28]
Actually, she worked for seven hours, so I'll solve for that.

7.20 x 3 = 21.6

6.75 x 4 = 27

21.6 + 27 = 48.6

48.6 /2 = 24.3

Her average should be $24.3  If she did work six hours, just multiply 6.75 x 3 and do what I did.
