The rate of change is constant in each table. Find the rate of change. Explain what the rate of change means for the situation Time (days):3,4,5,6 cost($):75,100,125,150

The rate of change is 25 and that means the cost per day is $25

Step-by-step explanation:

Since we have a constant rate of change, we can select any two points, apply the slope formula

The slope formula is;

m = (y2-y1)/(x2-x1)

(x1,y1) = (3,75)

(x2,y2) = (6,150)

m = (150-75)/(6-3) = 75/3 = 25

What the rate of change means here is that the cost per day is $25

step-by-step explanation:

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
