The answer, at least what I got, is 17.375 . They'd have to open an eighteenth package because the extra .375 is not in the original package, so I would go with B .
Answer:
y = -x + 9
Step-by-step explanation:
✔️Find the slope using (9, 0) and (7, 2):
Slope (m) = -1
✔️Find the y-intercept (b):
The line intercepts the y-axis when y = 9. Therefore, y-intercept (b) = 9
✔️Substitute m = -1 and b = 9 into y = mx + b
Thus,
y = -1(x) + 9
y = -x + 9

To solve for how much it would cost, we have to solve for the volume of the slab first, then multiply it by the given price of concrete.
Solving for the volume of the slab:
Since the given price is in cubic yard, it is easier to convert the given measurements from feet to yards first. Using the relation: 1 ft = 0.333 yd:
17 ft = 5.67 yards
2 ft = 0.67 yards
17ft x 17ft x 2ft = 5.67 yd x 5.67 yd x 0.67 yd = 21.54 yd^3
Multiplying this by $40.00 / yd^3:
21.54 x 40 = 861.59
Therefore, it will cost $861.59 to pour the slab.
