Answer:
The function shown on the graph has a smaller rate of change but a higher starting point.
Step-by-step explanation:
Looking first at the graph, we see that the intial potato production was 25000 lb, and that potato production tapered off to below 20000 lb over time.
Analyzing the equation for corn production: C(t) = 25,000 + 500 ln(t + 1), we see
that the initial production was 25000 lb per year and that this increases steadily with time.
Thus, answer A is false.
Answer B is false because at the outset the amounts of corn and potatoes was equal (25000 lb).
Answer D makes sense. Productions were both 25000 lb at the beginning, but the corn production rose steadily over time, exceeding the potato production.

Step-by-step explanation:
Answer:
$2000 was invested at 6% and $1000 was invested at 7%
Explanation:
Let:
x= the amount invested at 6% annual interest
y= the amount invested at 7% annual interest
The total amount invested was $3000. So,
x+y =3000
or
y=3000-x ===> Equation 1
Then, the total interest earned for the year was $190. So,
0.06x+0.07y=190 =====> Equation 2
Substitute y=3000-x into 0.06x+0.07y=190.
Substitute x=2000 into x+y =3000.
So,
Therefore, $2000 was invested at 6% and $1000 was invested at 7%.
