General tickets sell for $6 and adult $9. Sell at least 300 student and at least 500 adult. Costs $1 to advertise for adult and $.50 to advertise student. Have at most $400 for advertising. What is most profit that can be made? algebra inequalities
number of generals (student?) --- x , x ≥ 300
number of adults ----- y , y ≥ 500
ad cost = .5x + 1y , where .5x+y ≤ 400
profit = 6x + 9y - .5x - y
= 5.5x + 8y
The question cannot be answered
e.g. If we allow the min of each
x = 300, y = 500
profit = 5.5(300) + 8(500) = 5650
any increase in either x or y would increase the profit,
so the profit would just keep increasing.
What about maximum capacity of the venue ?
Did you mean
" sell at MOST 300 studens and at MOST 500 adults?"
Yes
To find the maximum profit, we need to determine the number of student and adult tickets to sell that will maximize profit while considering the given constraints.
Let's assume we sell x student tickets and y adult tickets.
Since we want to sell at least 300 student tickets, we can set the constraint: x ≥ 300.
Similarly, we want to sell at least 500 adult tickets, so we have the constraint: y ≥ 500.
Both of these constraints are inequalities.
Now, let's calculate the costs of advertising. It costs $0.50 to advertise a student ticket and $1 to advertise an adult ticket.
So, the total cost of advertising the student tickets will be 0.50x, and the total cost of advertising the adult tickets will be 1y. The total advertising cost cannot exceed $400, so we have the constraint: 0.50x + 1y ≤ 400.
To calculate the profit, we subtract the advertising cost from the total revenue.
The revenue from selling student tickets will be 6x since each student ticket sells for $6, and the revenue from selling adult tickets will be 9y since each adult ticket sells for $9.
The profit (P) can be given by the expression P = (6x + 9y) - (0.50x + 1y).
Now, our goal is to maximize the profit (P).
To solve this problem, we need to use linear programming techniques. However, since it involves multiple inequalities and constraints, we won't be able to solve it using simple algebraic expressions.
We can use computer software like Excel Solver or linear programming libraries in Python or other programming languages to quickly calculate the maximum profit by providing the constraints and objective function. The software will optimize the values of x and y accordingly.
Once the optimization problem is set up and solved, the software will provide the values of x and y that maximize the profit, as well as the maximum profit value.
