The answer is the second choice
For the answer to the question above,
<span>V(n) = a * b^n, where V(n) shows the value of boat after n years.
V(0) = 3500
V(2) = 2000
n = 0
V(0) = a * b^0 = 3500
a = 3500
V(2) = a * b^2
2000 = 3500 * b^2
b = sqrt (2000/3500)
b ≈ 0.76
V(n) = 3500 * 0.76^n
We can check it for n = 1 which is close to 2500 in the graph:
V(1) = 3500 * (0.76)^1
V(1) = 2660
And in the graph we have V(3) ≈ 1500,
V(n) = 3500 * (0.76)^3 ≈ 1536
Now n = 9.5
V(9.5) = 3500 * (0.76)^(9.5)
V(9.5) ≈ 258</span>
Divide 1 3/4 into 15. I like to change my fractions into decimals, so I will be using the decimal form of 1 3/4, which is 1.75
15 ÷ 1.75 = 8.571
Since there is still some left over, you would need to add one more roll. Therefore, you would need 9 rolls.
<span>(6c2) * (10c6) * (3c2)
Multiply
60c8 * 3c2
Multiply again
Final Answer: 180c10</span>
