The demand for personal computers in the home goes up with household income. For a given community, we can approximate the average number of computers in a home as q = 0.3453(lnx) - 3.048. x is greater than, or equal to, 10,000 and x is less than, or equal to, 125,000 where x is mean household income. Your community has a mean income of $20,000, increasing at a rate of $2,000 per year. How many computers per household are there?
