A bakery used 72 kilograms more butter this month than last month. The bakery used 240 kilograms of butter last month. I The increase in butter is ?% of the amount of butter used last month.

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.

Ithink the answer is d.

How many is in each case if there is 12 in each case it would be 40
