Answer: First, let's calculate the total cost of all the inputs:
Cost of grape concentrate = 2,450 * $0.07 = $171.50
Cost of granulated sugar = 54 * $0.50 = $27
Cost of lemons = 60 * $0.85 = $51
Cost of yeast tablets = 200 * $0.29 = $58
Cost of nutrient tablets = 250 * $0.11 = $27.50
Cost of water = 2,900 * $0.005 = $14.50
Next, let's calculate the amount of each input that is actually used:
Grape concentrate used = 2,450 * (1 - 0.02) = 2,401 oz
Sugar used = 54 * (1 - 0.10) = 48.6 lbs
Lemons used = 60 * (1 - 0.25) = 45
Yeast tablets used = 200
Nutrient tablets used = 250
Water used = 2,900 oz
Now, we can calculate the total cost of the inputs that are actually used:
Total cost of inputs used = $171.50 + $27 + $51 + $58 + $27.50 + $14.50 = $350.50
Finally, we can calculate the standard cost per gallon:
Standard cost per gallon = Total cost of inputs used / Number of gallons produced
Number of gallons produced = 50
Standard cost per gallon = $350.50 / 50 = $7.01 per gallon
Therefore, the standard cost per gallon of wine is $7.01.
