jim picks 16 quarts of berries. he needs 2 1/4 quarts to make a batch of jam. if he saves 2 1/2 quarts of berries to eat, how many batches of jam can jim make? write and solve and equation

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.
