The total cost y of printing x copies of a booklet is known for 4 lot sizes as follows:

,--------------,------,------,------,------,
| x (booklets) |  700 | 2700 | 3700 | 4400 |

'--------------'------'------'------'------'

Express the total cost as a sum of fixed cost and an additional cost per booklet printed. (use the method of Least Squares)
