If a petrol tank costs $2000.00 to  fill it up at 10°C ,how much extra  dollar must I pay to fill up the tank  at 50°C,if the petrol costs $50.00  per litre and its cubic expansivity  is 9.5×10^(−4) K^(−1) ?

((ΔV)/V)=9.5×10^(−4) ×(50−10)  =9.5×10^(−4) ×40  =0.038  Δcost=0.038×2000=76$
ΔVV=9.5×104×(5010)=9.5×104×40=0.038Δcost=0.038×2000=76$
