I need help, please.

Answers are as follows :

             2__                  3                     6

         $104                $146                 $252(+$20= )$272

Explanation:

by subtracting the $20 from $62 you get $42.

he recieves 20$ regardless of wether he cleans a room or not so to find answer one must multiply 42 by how many rooms and add the $20

80x^8−68x^6+16^5−20x^4−4x^3+8x^2
