Question 1166843: Can anyone help me with these. I am so slow with mathematics, thank you ! Godbless all.
Company ABYz makes 3 products: A, B, and C. To produce, each unit of A costs P176, each
unit of B costs P88, and each unit of C costs P44. ABYz must produce at least 20 units of A, 30
units of B, and 40 units of C. The total number of products should not be fewer than 200. How can
the company minimize the cost?

Question 1166592: How does famous former Seattle Mariner Ichiro’s record setting year of 2004 compare with Ted
Williams year when he was the last person to hit “over .400” in 1941? Ichiro hit .372 in 2004,
while the league average was .258. The standard deviation was .04. Ted Williams hit .406 and the
league average was .267 and the standard deviation was .03. (It was very hard to get accurate
numbers - different websites give different numbers.). More specifically, this question is asking
which person had a better relative performance. All you need to know about baseball is that a
bigger batting average is better,
