Problema Solution
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? (Round your answer to the nearest whole number.)
Answer provided by our tutors
N = 1,500 + 300 ln a (a ≥ 1)
a = $1000
N = 1500 + 300*(ln(1000))
N = 3,572 units
