Seven less than the sum of p and t is as much as 6.

P + t -7 =6

10+3-7=6

10+3=13

13-7=6

P=10 t=3

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
