A total of 6,000 cartons would be needed.
<h3>Miscellaneous calculation</h3>
Cost price = k dollars
Selling price = 4k/3 dollars
Assuming k = 1 dollar
Profit per carton = 4/3 - 1 = 1/3 dollars
2000/1/3 = 6,000 cartons.
Thus, irrespective of the cost price, 6,000 cartons would be needed to generate a profit of $2,000

Answer:
The size of the sample needed = 67.65
Explanation:
Given that :
The margin of error = 10% = 0.10
The confidence level = 90% = 0.90
Level of significance = 1 - 0.90 = 0.10
At ∝ = 0.10
Since the proportion of people that supported him/her is not given, we assumed p = 0.50
The margin of error formula can be expressed as:
Squaring both sides; we have:
n = 67.65
Therefore, the required sample size = 67.65
