An advertising agency conducted a survey and found that the number of units sold, N, is related to the amount a spent on advertising (in dollars) by the following formula:
N = 1,500 + 300 ln a (a ≥ 1)
How many units are sold after spending $1,000?

is the answer 933?
Assuming that the variable a stands for advertising dollars.
N (units sold) = 1500 + 300 * ln(3000)
N = 3572.33
Since you can't sell part of a unit I recommend rounding down and saying 3572 units were sold after $1000 was spent in advertising.
N (units sold) = 1500 + 300 * ln(3000)
N = 3572.33
