The correct exponential function to model the situation would be: y = 1,860,000(0.985)^x.
To find the amount after 12 years, substitute the value of x as 12 in the equation:
y = 1,860,000(0.985)^12
Calculating this, we get:
y ≈ 1,551,485
Therefore, the amount after 12 years is approximately 1,551,485.
Therefore, the correct answer is C.
Write an exponential function to model the situation, then find the amount after the specified time.
A population of 1,860,000 decreases 1.5% each year for 12 years.
A. y=1,860,000(1.05)^×; 3,340,293
B. y=1,860,000(1.05)-^×; 1,035,718
C. y=1,860,000(0.985)^×; 1,551, 485
D. y=1,860,000(0.95)^×; 1,005,070
