Answer: C. (25)/(1) dollars per day; the cost is $25 for each day.
$25/ 1 day or $25 a day
Step-by-step explanation:
Answer:
The rate of change is 25. It means the cost increased by $25 per day.
Step-by-step explanation:
The given table is
Time (days) Cost ($)
3 75
4 100
5 125
6 150
It means the graph of this constant function passing through the points (3,75) and (4,100).
If a line passing through two points, then the slope of the line is
Therefore the rate of change is 25. It means the cost increased by $25 per day.
Answer:

Step-by-step explanation:
You could calculate the area of the trapezoid and then subtract the area of the triangle.
Area of a trapezoid:

Plug values in:

Add 6 and 12:

Simplify:

Area of a triangle:

Plug values in:

Simplify:
A = 36
Subtract the area of the triangle from the area of the trapezoid
54 - 36 = 18
You could also calculate the area of the shaded region by assuming that they're congruent meaning the base would be half of 6 which is 3 and the height would be 6 so the area of one would be 1/2 (6)(3) but since they're is 2 you wouldn't need the 1/2 since multiplying by 2 would cancel it out so the area would be (6)(3) = 18
