Total purchase = (unit cost)(# of pounds purchased)
Here, that total is ($0.98/lb)(3.5 lb) = $3.43 (answer)
Solving inequalities is just like solving any other Algebraic problem...look to P.E.M.D.A.S. (Parenthesis, Exponents, Division, Addition, Subtraction). So lets take a look at this problem now.
1200 + 0.075x

3300
Subtract 1200 from both sides...
0.075x

2100
Now divide by 0.075...
x

28000
NOTE: If you divide or multiple by a negative number while solving inequalities, you must flip the sign. Ex: You answer would be x

28000 if you would've multiplied or divided by a negative.
F is odd if and only f f(-x) = -f(x) so f(x) = 0 works because 0 = 0 always.
f is even if and only if f(-x) = f(x) so f(x) = 0 works because there's no x term so nothing changes. 0 = 0.
Answer:
The function is 
Step-by-step explanation:
From the question we are told that
The rate of growth is
The total profit is
$25,000
The time taken to make the profit is 
From the question
is the rate of growth
Now here x represent the time taken
Now the total profit is mathematically represented as

So using substitution method
We have that


So

![p(x) = {\frac{1}{2} [ e^{-u}} +c ]](https://tex.z-dn.net/?f=p%28x%29%20%3D%20%20%7B%5Cfrac%7B1%7D%7B2%7D%20%5B%20e%5E%7B-u%7D%7D%20%2Bc%20%5D)
recall
and let 
At x = 2 years
$25,000
So
Since the profit rate is in million
$25,000 =
$0.025 millon dollars
So
=>
So the profit function becomes
