lana66690 [7]

Answer:

Correct choice is B

Step-by-step explanation:

The exponential regression model can be written as exponential function

y=a\cdot b^x.

Then

5,000=a\cdot b^0=a,\\ \\5,510=a\cdot b^2\Rightarrow 5,510=5,000\cdot b^2,\\ \\b^2=\dfrac{5,510}{5,000}=\dfrac{551}{500}\Rightarrow b\approx 1.05.

Thus,

y=5,000\cdot (1.05)^x.

When x=12, you get

y(12)=5,000\cdot (1.05)^{12}\approx \$8,980.
