Given:
Amount of gas she had when she arrived = 4 gallons
Pump rate, r = 1/10 gallons per second
To find the amount of gas she has after s seconds, we have the equation below:
[tex]T=\frac{1}{10}s+4[/tex]Where T represents the total amount of gallons in her tank after s seconds
ANSWER:
[tex]T=\frac{1}{10}S+4[/tex]
