The answer is this hopefully this helped the only thing you need to do is just put the steps so just do - 12÷3 or you can ask somebody to help you to divide.

Answer:
The answer is below
Step-by-step explanation:
Plotting the following constraints using the online geogebra graphing tool:
x + 3y ≤ 9 (1)
5x + 2y ≤ 20 (2)
x≥1 and y≥2 (3)
From the graph plot, the solution to the constraint is A(1, 2), B(1, 2.67) and C(3, 2).
We need to minimize the objective function C = 5x + 3y. Therefore:
At point A(1, 2): C = 5(1) + 3(2) = 11
At point B(1, 2.67): C = 5(1) + 3(2.67) = 13
At point C(3, 2): C = 5(3) + 3(2) = 21
Therefore the minimum value of the objective function C = 5x + 3y is at point A(1, 2) which gives a minimum value of 11.
Answer:
(1) The total cost under Plan A is <u>$92</u> and the total cost under Plan B is <u>$515</u>.
(2) The total cost under Plan A is <u>$92</u> and the total cost under Plan B is <u>$1,030</u>.
Step-by-step explanation:
<u><em>The question is incomplete, so the complete question is below:</em></u>
Now, to find (1) total cost for each of the two plans. (2) Total cost under each of the two plans, if sister doubles her monthly usage to 3,500 minutes and sends 3,300 texts.
<h3>(1) </h3>As, the Plan A is for unlimited talk and text
Cost of the Plan A = $92.
<u><em>Now, to find the cost under Plan B:</em></u>
According to question:
Rate of call per minute is $0.20 and per text is $0.10.
Calls she uses currently is 1,750 minutes and text 1,650.
<u><em>So, to get the cost of Plan B:</em></u>
Thus, Plan B costs $515.
<h3>(2)</h3><u><em>Now, to get the total cost as, sister doubles her monthly usage to 3,500 minutes and sends 3,300 texts.</em></u>
As, the Plan A is same in both cases and is for unlimited text and calls.
So, cost of Plan A = $92.
As, the monthly usage is double.
Calls in minutes are 3,500.
Texts are 3,300.
<u><em>Now, to get the total cost under Plan B:</em></u>
Hence, the cost of Plan B = $1,030.
Therefore, (1) The total cost under Plan A is $92 and the total cost under Plan B is $515.
(2) The total cost under Plan A is $92 and the total cost under Plan B is $1,030.
