Advanced science students are not representative of all of the students in the school
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:
$82.68
Step-by-step explanation:
Original price of mint - $106
Percent discount = 22%
Discount price = 22/100 * 106
Discount price = 0.22 * 106
Discount price = $23.32
New value = Original price - discount price
New value = 106 - 23.32
New value = 82.68
Hence the new value of the figure will be $82.68
