Walden’s family is shopping for a reclining chair. The chair the family has decided on has a retail price of $800 plus 5% tax at four stores. Each store is offering a different promotion. Which store has the best deal?

Iwould say false, not positive but if prices went up for both stores, technically there will be less buyers?

A. is the answer in this question

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.
