Answer: See Annex
z (max) = 190
x = 10
y = 20
Step-by-step explanation:
z = 5*x + 7*y to maximize
Subject to:
x + y ≤ 30
2*x + y ≤50
2*x - y ≥ 0
x≥= y ≥0
Answer:
$160,000 to $220,000 = 37.5% increase
Step-by-step explanation:

Answer:
Each shirt costs 12 dollars.
Each pair of pants cost 40 dollars.
Step-by-step explanation:
<u>Let x represent the shirts </u>
<u>Let y represent the pair of jeans</u>
10x + 4y = $280
12x + 5y = $344
<u>Use elimination method to eliminate y</u>
• Multiply the entire first equation by 5.
• Multiply the second entire equation by -4.
5(10x +4y = $280)
-4(12x + 5y = $344)
50x + 20y = 1400
-48x -20y = -1376
2x = 24
x = 12
Each shirt costs 12 dollars.
<u>Solve for how much each pair of jeans costs.</u>
10(12) + 4y = 280
120 + 4y = 280
4y = 160
y = 40
