The gasoline gauge on a van initially read 1/4 full. when 10 gallons were added to the tank, the gauge read 2/3 full, how many more gallons are needed to fill the tank?

3; 9 is 8 to -4

step-by-step explanation:

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
