When the rent per unit is $580 per month all 50 units are occupied. However when the rent is $625 per month, the average number of occupied units drops to 47. Assume that the relationship betweeen the monthly rent p and the demand x is linear. Write the equation of the line giving the demand x in terms of the rent p. Use this equation to predict the number of units occupied when the rent $655. Predict the number of units occupied when the rent is $595.  </SPAN>\n" );
