I want to buy a car that cost 36,718 I also have a 9% sales tax to keep in mind

40,022.62

Step-by-step explanation:

9% of 36,718=3304.62

36,718+3304.62=40,022.62

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
