She pumped gas into her car at a rate of io gallon persecond. How many gallons of gas were in the tank after s seconds?4.

Answer 1

At the gas station, Chrissy already has 4 gallons of gas, and she pumped gas at rate of 3/10 per second, so at s seconds she has:

`\text{gas}=4+(3)/(10)s`

In the equation above, the 4 is the initial amount of gas in the car (4 gallons) and the other term is the gallons pre second she pumped.
