Hi!
We need to find the cost per ounce.
2.10/16 = 0.13125
It costs 0.13125 per ounce.
Now find the cost of 12 ounces.
12 * 0.13125 = $1.58
The answer is $1.58
Hope this helps! :)

Let's make the width 'x'.
And the length 'x+4'.
Perimeter is adding up ALL the sides.
Add: x + x + 4 + x + x + 4.
Simplify:
x + x + 4 + x + x + 4 = 4x + 8
Well, you lost the original $100 and then you gained back $70 but gave away $70 worth of merchandise, so it evens out and you lost $100 in total
Create formulas!
x=number of adult tickets
y=number of student tickets
x+y=644 <em>total sold</em>
56+y=x <em>student was 56 less than adult</em>
Perform substitution
(56+y)+y=644
56+2y=644
2y=588
y=294
Substitute y into the formula we created
x+294=644
x=350
350 adult tickets were sold.
It is related to the distributive property because you could show the distributive property by using the areas of rectangles.
