Given:
Regular price = r
discount rate = 30%
coupon = $5 off any single item at the store
expression: 3(r - 0.3r) - 5
C.) 3(0.7r) - 5 represents the total cost before tax.
3(r-0.3r) - 5 ⇒ 3(0.7r) - 5
The coupon can only be used once because the problem stated any single item not every single item purchased.
Answer: It's already in it's simplest form.
* Hopefully this helps:) Mark me the brainliest:))!!!
in a right-triangle, like in the 1st Quadrant, cosine and sine are complements, so then
sin(x) = cos(90° - x)
cos(x) = sin(90° - x)
for this case, sin(<u>90°</u>) = cos(90° - <u>90°</u>), or just cos(0°) = 1.

is there more to the question?
