Answer:

a) Price is linearly dependent on size of home

b) asking price= $110,570

$5500 is spread

Explanation:

Price = 47.87+0.062(size)

a) the equation follows y=mx+c or linear equation model

b) asking price is the offer price or the price the seller says he/she will accept for his/her property

Price= 47.87 +0.062(1100)

Price= 116.07 × 1000

Asking price= 116070-5500

                    = $110,570

5500 is the spread between asking prcce and bid price. It tells about the market maker's or agent's profit.
