To qualify for Gold status at Awesome Airlines, one must fly less than 27500 but at least 9900 miles each year. If Gerald takes a 550-mile round-trip flight when visiting

his parents, how many times does Gerald need to visit his parents each year to attain Gold status? Express your answer in interval notation

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.
