The table contains data on sales of three homes. Price P is measured in thousands of dollars, home size S is in square feet, and condition Cis rated on a scale from 1 to 10, where 10 represents excellent condition. The variables were found to be related by the equation P = a + bS + cC.

(a) Use the table to write a system of linear equations whose solution gives a, b, and c. Solve this system of linear equations. 

(b) Estimate the selling price of a home with 1800 square feet and a condition of 7.
