Answer:
0.2x² - 0.2x - 42 = 0
Step-by-step explanation:
Number of counters = x
Number of blue counters =7
Probability, p = required outcome / Total possible outcomes
P(Sam picks blue ) : = 7/x
P(jill picks blue) = 6/(x - 1)
P(Sam picks blue) * P(Jill picks blue) = 0.2
7/x * 6/(x-1) = 0.2
42/x(x - 1) = 0.2
42 / x² - x= 0.2
42 = 0.2(x² - x)
42 = 0.2x² - 0.2x
0.2x² - 0.2x - 42
Answer:
36¢ per pound
Step-by-step explanation:
In 1995, the price per pound was ...
($24.7 million)/(15 million lb) = $1.6467/lb
In 2000, the price per pound was ...
($31,297,583)/(15,616,728 lb) = $2.0041/lb
The difference was ...
$2.0041 -1.6467 = $0.3574 ≈ 36¢ . . . per pound
_____
In a calculation such as this, you want to keep enough significant digits so that you can appropriately round the final answer. Here, the result would be different if intermediate values were rounded to whole cents.
