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. let x = the number of gallons that chris bought at the first station and y = the number of gallons chris bought at the second station. solve the system of equations to find the number of gallons that chris bought at the second station. 5 8 12 20

In this question it is given that,

Let x = the number of gallons that Chris bought at the first station and y = the number of gallons Chris bought at the second station.

So we have

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49
