Answer:
Brand A is the better deal!
Step-by-step explanation:
Let's start by comparing.
We know brand B has the following cost: 5 ounces = $3.75
10 ounces $7.50 and 16 ounces = $12
Now check the graph.
6 ounces cost $3
12 ounces cost $6
20 ounces cost $10
I don't think we need to look any further but brand A is the better deal!
Answer:
We readily separate the variables and integrate:
∫dP/P=∫(k+bcos2t)dt
ln P=kt+(b/2)*sin2
t+ln C
Clearly C = Po, so we find that P(t) = Poexp(kt + (b/2)* sin 2
t). The 271- curve with the typical numerical values P_o = 100, k = 0.03, and b = 0.06. It oscillates about the curve which represents natural growth with P_o and k = 0.03. We see that the two agree at the end of each full year.
