Chris stopped for gas twice on a long car trip. The price of gas at the first station was $1.45 per gallon, and the price of gas at the second station was $1.55 per gallon. On the trip, Chris bought a total of 20 gallons of gas and spent $29.80.
If x = the number of gallons that Chris bought at the first station, and y = the number of gallons Chris bought at the second station, which system of equations could be used to find the number of gallons of gas Chris bought at each station.
1.
1.45 x + 1.55y = 20 and x + y = 29.80
2.
x + y = 20 and 1.45x + 1.55y = 29.80
3.
x + y = 20 and 1.45x - 1.55y = 29.80
4.
xy = 20 and 1.45x + 1.55y = 29.80
