Answer:
The cost to fill the tank is $ 0.75.
Step-by-step explanation:
Given,
The volume of the gas tank = 288.75 in³,
Since, 20 % of tank is full by the gas,
⇒ The total gas in the tank = 20 % of the volume of the tank
= 20 % of 288.75
= 0.2 × 288.75
= 57.75 in³
= 0.25 gallon ( 1 gal = 231 in³ ⇒ 1 in³ = 1/231 gallon ),
According to the question,
The cost of 1 gallon of gas = $ 3.00
⇒ The cost of 0.25 gallon of gas = 0.25 × 3.00 = $ 0.75
Hence, the cost to fill the tank is $ 0.75.
