You have:
<span>Cost in dollars --> $2.89 </span>
<span>Total ounces --> 4.25 </span>
<span>But you want to know the per unit cost for *1* ounce. </span>
<span>You have the right method. You want cost ($) per ounce so put the price over the amount in ounces. </span>
<span>2.89 / 4.25 = x / 1 </span>
<span>If you notice, since the denominator is 1, this is simply: </span>
<span>x = 2.89 / 4.25 </span>
<span>So the unit cost is just $2.89 divided by the number of ounces (4.25). </span>
<span>Plug that into your calculator and you get: </span>
<span>0.68 </span>
<span>That's in dollars. So if you want it in cents, move the decimal point 2 places to the right. </span>
<span>Answer: </span>
<span>$0.68 per ounce </span>
<span>or </span>
<span>68 cents per ounce</span>

Answer:
Part 1)
A
Part 2)
C
Step-by-step explanation:
1)
We are given:
And that:
And we want to now for which values of x is h(x) undefined.
So, by substitution:
Remember that for rational functions, the function will be undefined if and only if the denominator is 0.
This is because we cannot divide by 0.
So, to find the values for which the denominator is 0, set the denominator to 0 and solve for x. Therefore:
Add 9 to both sides:
Take the square root of both sides. Since we are taking an even-root, we will need plus/minus. Therefore:
So, h(x) is undefined for ±3.
Our answer is A.
2)
We are given:
And we want to find:
So:
Distribute:
Combine like terms:
Rewrite:
Factor out:
So, our answer is C.
