Answer:
Look just at finding the linear model. Two points. Use price per gallon for x and gallons per hour sold for y. Your two points (x,y) are (2.15,1600) and (2.55,800).
Slope m=%281600-800%29%2F%280.15-0.55%29
m=800%2F0.40
m=2000
Using point-slope form for a line, and the lower-y point,
y-800=2000%28x-2.55%29
highlight%28y=2000%28x-2.55%29%2B800%29
Answer:
The turtle population's rate of growth will be 32 turtles per year after 2 years and 248 per year after 6 years.
Ten years after the conservation measures are implemented the population will be 3260 turtles.
Step-by-step explanation:
To find the rate of growth of the turtle population at any time <em>t</em> you need to find 

In particular, when t = 2 and t = 6, we have

so the turtle population's rate of growth will be 32 turtles per year after 2 years and 248 per year after 6 years.
The turtle population at the end of the tenth year will be

2/5 = 0.4 as a decimal.
Now subtract:
10.25 - 7.4 = 2.85 ounces are left
I think that is arithmetic i not totally sure
