Emmy Swanson · Answer 1

Assuming there was only 1 visit

V = visit = 80

S=rooms sprayed = 35

x=amount of rooms sprayed

(80) + x (35) = 395

subtract 80 from both sides

x (35) = 315

divide 35 from both sides

x=9

9 rooms were sprayed

Ruth Burgess · Answer 2

395-80=315

315/35=9

9 rooms were sprayed
