Please, I need help with a calculation

How do I calculate this? The answer is the fourth option d) but I don't know how to get to it, I just can't get it right.

A manufacturer's supply equation is p=log(1000+q), with q the number of units supplied at price p.

The number of units supplied if the price is $5 is:
a) 2
b) 100
c) 99 997
d) 99 000

Re: Please, I need help with a calculation

First put in 5 for p



Then use both sides of the equation as an exponent with base 10



Which simplifies by inspection to

100 000 = 1000 + p

One more step and you're done.
