Answer:
maximum profit is$2400 when 4 necklace and 3 brackets are made.
Step-by-step explanation:
Total gold = 18 ounces
Total platinum = 20 ounces.
let X₁ represents the necklace and X₂ represents the bracelets.
A. Linear Programming Model
maximize:
with constraints:
for gold:
---(1)
for platinum:
---(2)
The demand for bracelets is no more than four i.e.
---(3)
B. Graphical Analysis
Final answer:
To maximize profit, formulate a linear programming model with constraints for the number of necklaces and bracelets to produce. Solve the model using graphical analysis to find the optimal solution.
Explanation:
To formulate a linear programming model for this problem, let x be the number of necklaces to produce and y be the number of bracelets to produce. The objective is to maximize profit, which can be expressed as: Profit = 300x + 400y. The constraints are: 3x + 2y ≤ 18 (gold constraint), 2x + 4y ≤ 20 (platinum constraint), 0 ≤ x ≤ infinity (non-negativity constraint), and y ≤ 4 (demand constraint).
To solve this model using graphical analysis, graph the feasible region determined by the constraints. The feasible region is the region in which all constraints are satisfied. The optimal solution will be at one of the corner points of the feasible region. Calculate the objective function at each corner point and select the one that maximizes profit.

Answer:
Bloomberg Business week NorthAmerica Subscribers
; Quantitative ; Qualitative ; No ; Yes ; No
Step-by-step explanation:
Sample size = 2861
Percentage respondent with annual income ≥ 75000 = 59%
Percentage having an American Express credit card
1.What is the population of interest in this study?
Bloomberg business week NorthAmerica Subscribers
2. Quantitative
Annual income is quantitative because it is numeric, that is repress red by numbers which can be used to perform sensible numerical computation such as additions, mean, multiplication and so on.
3.Qualitative
No ; ownership of an American express card is a Qualitative variable as it will take responses as (yes or no), even when represented or coded as numbers, it will make no numerical sense to peform mathematical calculations with it.
4.
No ; time series data has to do with data collected with respect to a particular month, year or seasonal data.
5. Determine whether the following two statistical inferences may be made based on the sample data collected.
An estimated 59% of the population of subscribers has an annual income of $75,000 or more.
Yes ;
An estimated 60% of the population of subscribers has an American Express credit card.
No ; the research says 50% and not 60%
