$0.46 per ounce I think. Not 100%, a guess.
Answer/Step-by-step explanation:
Use equation y = mx+b
m is the slope and in the place for m is 15
b is the y intercept and because there is no y-int. it would be 0
Since the y-int is 0 then it is proportional.
This would be a positive slope.

Answer:

Step-by-step explanation:
<u>Step 1: Make the denominator a whole number</u>
<u />


<u>Step 2: Divide</u>
<u />

Answer: 
Equate P as 62.10 since we are looking for the MAX value for x (then a legitimate one if necessary)
(20 + 0.5x) + (3 + 0.075x) = 62.1
= 0.575x + 23 = 62.1
x = (62.1-23)/0.575
x = 680
38.72 divided by 1.1 equals to 35.2.
