The answer is domain. hope this helps...
You just do 280 x 1.17= 327.6
Answer: €327.6
(0,6)(1,3)
slope(m) = (3 - 6) / (1 - 0) = -3
y - y1 = m(x - x1)
slope(m) = -3
(1,3)...x1 = 1 and y1 = 3
now we sub
y - 3 = -3(x - 1) <===
Number one is the correct one i think
I'm sorry if I wasn't there to help but thank the others, and thank you :)
