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>
28:
1*28 = 28

Factors of 15 are 1, 3, 5, 15.
36:
1*36 = 36
2*18 = 36
3*12 = 36
4*9 = 36
6*6 = 36
Factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36

Answer:
$132
Step-by-step explanation:
First we need to find the total number of woods required. This would be total area of fence divided by area of each wood. Remember to convert inch into feet.

Now we know the total number of planks, we need to find what is the cost of each plank. We know that one wood plank area is 2 sq. ft ( 6*0.33333). Therefore, the cost of each plank is = cost per area(sq.ft) multiply by total area (sq. ft).
cost per plank = 2 * $1.10 =$2.20.
We have total planks = 60 units and we have cost per plank = $2.20.
So, we can find total cost as 60*2.20= $132

Answer:
supplementary angle to x = 180 - 31 - 43 - 32 = 74°
x = 180° - 74° = 106°
