By looking at the graph, it seems Equation A and Equation C both intersect at (0, 8). So the first answer is correct.
Greetings!
To find equivalent ratios, you must divide/multiply both terms of the ratio by the same number:
Examples:
1) 14*2=28
2*2=4
28:4
2) 14/2=7
2/2=1
7:1
3) 14*100=1400
2*100=200
1400:200
Hope this helps.

Answer:
f(t)=18,000(0.85)^t
Step-by-step explanation:
18,000 is the a value, and since it is depreciating 15% becomes -.15
so we are going to set it up like f(t)=18,000(1-0.15)^t
Final answer is f(t)=18,000(0.85)^t
To find how much gasoline costs each mile, you do 485/500. Reduce it to 97/100, or 97 cents. So .97m = c. B. Replace m with 1200 to get .97(1200) = c. C, after doing the math, you get 1164 dollars. C. Replace c with 820. Your equation is .97m = 820. Divide both sides by .97 to get m = about 845.36 to the nearest hundredth, 845.4 to nearest tenth, or 845 to the nearest whole mile. I recommend using the nearest hundredth to be precise, but that's up to you.
