Question

card 15
a container releases fuel at a constant rate of 5 gallons per second. the variable y represents the amount of fuel remaining in the container and x represents the number of seconds that have passed since the fuel started dispensing.
if the tank begins with 103 gallons, how many gallons will remain after 2 seconds?

Explanation:

Step1: Find fuel released in 2 seconds

Fuel rate is 5 gallons per second. In 2 seconds, fuel released = \(5\times2 = 10\) gallons.

Step2: Calculate remaining fuel

Initial fuel is 103 gallons. Remaining fuel \(y=103 - 10=93\) gallons.

Answer:

93
