**PLS HELP** James bought 22 candy bars for $137. If king size candy bars cost $8 and regular size cost $5, how much of each candy bar did he buy?

One equation looks like: x+y=22

Find the other equation and solve the system.

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.
