There are two gas stations in Stuartville, Fred's Gas and George's Gas. At Fred's Gas, one driver buys 12 gallons of gas for $25.80, and another driver buys 15 gallons of gas for $32.25. At George's Gas, the cost of gas is represented by the equation y=2.21x, where y is the total cost, and x is the number of gallons. Which gas station has cheaper gas?

URGENT PLEASE

The variables should add up to equal 1

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
