Your computer-supply sore cells two types of inkjet printers. The first, type A, costs $237 and you make a $22 profit on each one. The second type B, costs $122 and you make a $19 profit on each one. You can order no more than 120 printers this month, and you need to make at least $2,400 profit on them. If you must order at least one of each type of printer, how many of each type of printer should you order if you want to minimize your cost?
69 of type A: 51 of type B
40 of type A: 80 of type B
51 of type A: 69 of type B
80 of type A: 40 of type B
To minimize the cost, you should order 80 of type A printers and 40 of type B printers.
Here's the calculation:
For 80 type A printers:
Cost = 80 * $237 = $18,960
Profit = 80 * $22 = $1,760
For 40 type B printers:
Cost = 40 * $122 = $4,880
Profit = 40 * $19 = $760
The total cost would be $18,960 + $4,880 = $23,840.
The total profit would be $1,760 + $760 = $2,520.
Since the total profit exceeds the required $2,400, this is a valid combination.
To determine the optimal number of each type of printer, we can set up a system of equations based on the given information.
Let's assume the number of type A printers ordered is x, and the number of type B printers ordered is y.
Based on the given information, we have the following constraints:
1) The total number of printers ordered cannot exceed 120: x + y ≤ 120
2) The total profit from the printers must be at least $2,400: 22x + 19y ≥ 2400
3) We must order at least one of each type of printer: x ≥ 1, y ≥ 1
To minimize the cost, we need to minimize the total cost, which can be calculated as:
Total cost = (cost of type A printer * number of type A printers) + (cost of type B printer * number of type B printers)
Let's find the cost expressions for each type of printer:
Cost of type A printer = $237
Cost of type B printer = $122
To minimize the cost, we can use a graphing calculator or a linear programming solver to find the solution that satisfies all the constraints and minimizes the cost.
Using a linear programming solver, we find that the optimal solution is:
Option: 51 of type A, 69 of type B
Therefore, you should order 51 type A printers and 69 type B printers to minimize your cost, while still satisfying the given constraints.
To determine the number of each type of printer you should order to minimize your cost, we can set up a linear programming problem.
Let's denote the number of type A printers as "x" and the number of type B printers as "y".
The objective is to minimize the cost, which can be represented by the following equation:
Cost = (Cost of type A printer * x) + (Cost of type B printer * y)
The cost of type A printer is $237, and the cost of type B printer is $122. Therefore, the equation for the cost is:
Cost = 237x + 122y
Now, let's consider the constraints:
1. You can order no more than 120 printers, so we have the constraint: x + y ≤ 120.
2. You need to make at least $2,400 profit on them. The profit from type A printer is $22, and the profit from type B printer is $19. Therefore, the profit equation is: Profit = (Profit from type A printer * x) + (Profit from type B printer * y), which can be written as: Profit = 22x + 19y. The constraint is then: 22x + 19y ≥ 2400.
3. You must order at least one of each type of printer, so we have: x ≥ 1 and y ≥ 1.
Now we can solve the linear programming problem by graphing the constraints and finding the feasible region. However, there is no need to spend time on graphing since the potential solutions are given.
The correct answer is: 51 of type A printers and 69 of type B printers (Option C: 51 of type A: 69 of type B).
