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:
A , B , C
Step-by-step explanation:
1) find the slope of the given line
slope = (-a/b) = (-8/4) = -2
two parallel lines have the same slope
A : correct
B : (-a/b) = -16/8 = -2 (correct)
C : correct
D : wrong (2 is different from -2)
Answer: x= 12 and MNQ= 25 degrees
3x - 11 + 65 = 90
3x + 54 = 90
3x = 36
x = 12
plug in the value of x to get MNQ
3(12) - 11
36 - 11
25
