Acomputer supplies store is having a store wide sale this weekend. and inkjet printer that normally sells for $179 is on sale for $143.20 . what is the percent discount of the sale price

Hey again!

i don't know if i am doing this correctly but i will give it a go

179 - 143.20 = 35.8

179 / 35.8 = 5

so this would mean from 179 to 143.20 their is a 5% discount

Hope This Helps!

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.
