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: -4
The formula for slope is rise/run. This means that between two points, you have to see the distance going up and down/ left and right.
Looking at points (0,-1) and (3,-1), you can see that the height difference is 4 units. This means that the rise is 4.
rise/run
4/run
Left and right, the difference is only one unit.
4/run
4/1
4
This graph is also negative, so let’s add that in.
-4
