a) C = 14w + 48
b) slope =
Step-by-step explanation:
A) Let C represent the cost of the waste
w represent the number of kilograms of waste
when cost = $1448, the amount of waste = 100kg
(w, C) = (100, 1448)
when cost = $2498, the amount of waste = 175kg
(w, C) = (175, 2498)
we need to find the slope of the points we were given
Slope formula is given as:
B) slope = 14
Slope = cost/amount of waste
In units, we are dividing the dollar by the kilogram = $/kg
The units of the slope is dollars per kilogram (option D)
C) Vertical intercpet is the y -intercept
From our calculation, y-intercept is = b = 48
Hence, the vertical intercept is 48
The y-intercept is the intial value or initial cost of the waste. This is the cost when the kilogram of waste is zero
C = 14w + 48
w = 0
C = 14(0) + 48
C =48
Since the unit of C is dollars. Then the unit of the intercept will also be in dollars (option D).
