Find a recipe in a book or online that includes the amount of salt as a fraction. model how to find the amount of salt needed when the recipe is doubled

I will give you a example.

If you find a recipe with 1/3 tablespoon salt, it would be 1/3+1/3=2/3

Never change the bottom number (Denominator) unless the two denominators are diffrent.

Num of plants = (original#ofplants)*(1.6)^t

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.
