Y=4(5/6)^x O exponential growth; 4
O exponential decay; 4
exponential growth; 0
exponential decay: 5

it is true

step-by-step explanation:

all the combinations add up i used   calculator

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
