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

Step-by-step explanation:
this is because to answer those questions you need to survey multiple different people, you'd need more than just an answer if you were to find the average of something. For the other questions they're very direct and only have one answer. Therefore you wouldnt need a statistical process for the other questions and only for a and e.
