100y+x=230
150y+x=320
Y being the price per kilogram of steel bar, x being the added delivery fee.
If you were to solve the equaltion it would go x=230-100y by changing the first equation around the replacing that for the x int he second group, so you would get 150y+230-100y=320 or 50y=90 So Y=9/5dollars per kilogram. Or $1.8per kilogram, the delivery fee being $50
Answer: Probability
Step-by-step explanation:
Probability is the number of ways an event can occur, happen or take place (number of outcomes), f, divided by the total number of outcomes, N, is the probability of of an event occurring,
Therefore; P(E) = f/N. E.g When a dice is tossed, there is a 1/6 chance of getting a 3 because a dice has six sides.
