Using coupons, you spend $135 grocery shopping. this is 75% of the total retail price of the groceries. how much would you have spent if you had not used the coupons?

Let x be the total price. And you paid 75% of it which is $135.

x * 75/100 = 135
x = 180
You would have paid $180 if you had not used coupons.

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.

sorey ik so sorey i need and need to answer a few
