tigry1 [53]

Answer:

Explanation:

In a perfectly competitive industry, no single buyer nor seller will be able to influence prices thus marking the forces of demand and supply (the invisible hand) the determinant of pricing.

Hank Itzek manufactures and sells homemade wine, and he wants to develop a standard cost per gallon. The following are required

Slav-nsk [51]

Answer: $4.140 per gallon

Explanation:

Costs including wastage for 210 gallons:

3,300 ounces of grape concentrate at $0.03 per ounce:

= $3,300\times\frac{0.03}{0.99}$

= 100

357 pounds of granulated sugar at $0.36 per pound :

= $357\times\frac{0.36}{0.85}$

= 151.2

294 lemons at $0.63 each = $294\times\frac{0.63}{0.70}$

= 264.6

840 yeast tablets at $0.28 each = 840 × 0.28

= 235.2

1,050 nutrient tablets at $0.11 each = 1,050 × 0.11

= 115.5

3,100 ounces of water at $0.001 per ounce = 3,100 × 0.001

= 3.1

Hanks estimates that,

1% of the grape concentrate is wasted

15% of the sugar is lost

30% of the lemons cannot be used

Hence,

Cost for 210 gallons = 100 + 151.2 + 264.6 + 235.2 + 115.5 + 3.1

= $869.6

Hence, cost per gallon = $\frac{Cost\ for\ 210\ gallons}{210\ gallons}$

= $\frac{869.6}{210}$

= $4.140 per gallon
