Question 714497
N = 4,500 + 300 ln a
Just replace the "a" with 1000:
N = 4,500 + 300 ln 1000
Then use your calculator to simplify the right side. (ln first, then times 300, then add 4500). The value you get for N will be some decimal number. Since N represents the number of units sold and since fractions of a unit do not make sense, round your value for N to the nearest whole number.
