6x + 3y = 79.5
3x + 2y = 41 y = -3/2x + 41/2 y = -1.5x + 20.5
6x + 3(-1.5x + 20.5) = 79.5
6x - 4.5x + 61.5 = 79.5
1.5x + 61.5 = 79.5
1.5x = 18
x = 12
Each shirt costs $12.
Now insert that number into the x to find the cost of each tie.
3(12) + 2y = 41
36 + 2y = 41
2y = 5
y = 2.5
Each tie costs $2.50.
The correct answer is 400.

Answer:
C. 42
Step-by-step explanation:
<em>PEMDAS</em>
1. Parentheses: (4 + 2) = <em>6</em>
6² + 3 • 2
2. Exponents: 6² = <em>36</em>
36 + 3 • 2
3. Multiplication/Division: 3 • 2 = <em>6</em>
36 + 6
4. Addition/Subtraction: 36 + 6 = <em>42</em>
