Option B
2 notebooks for $ 0.60 expressed as unit rate is $ 0.30 per notebook
<h3><u>Solution:</u></h3>
We have to express ratio as unit rate
Given that, 2 notebooks for $ 0.60
Number of notebooks = 2
Cost of 2 notebooks = $ 0.60
So we have to find cost of 1 notebook

So unit rate = cost of 1 notebook = $ 0.30
So 2 notebooks for $ 0.60 as unit rate is $ 0.30 per notebook

Answer:
336 cm^2
Step-by-step explanation:
The area of a trapezoid is given by the formula ...
A = 1/2(b1 +b2)h
where b1 and b2 are the base lengths, and h is the height. Filling in the values shown gives ...
A = (1/2)(28 +14)(16) = (1/2)(42)(16) = 336 . . . . cm^2

<u>Algebra I</u>
Compounded Interest Rate Formula: 
- <em>A</em> is final amount
- <em>P</em> is principle amount
- <em>r</em> is rate
- <em>n</em> is compounded rate
- <em>t</em> is time
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify given variables</em>.
<em>P</em> = $47,323.15
<em>r</em> = 0.05
<em>n</em> = 1
<em>t</em> = 3
<u>Step 2: Find Interest</u>
- [Compounded Interest Rate Formula] Substitute in variables:

- Evaluate:

∴ Jack will <em>gain</em> $7,459.31 and have a net balance of $54,782.50.
