<span>The answer is B. C(n) = 0.75n - 0.25.
Let n be the number of pieces. The price for 1 piece is $0.75. The price C for n pieces without a coupon is n * $0.75: C(n) = 0.75n. The coupon value is $0.25. So, this value must be subtracted from the total price of n pieces. Since the coupon values in independent on the number of pieces, the price C for n pieces with the coupon will be: C(n) = 0.75n - 0.25. Therefore, the correct choice is B.</span>
Answer:
C
Step-by-step explanation:
Volume in math means s the amount of space in a 3D object.
the formula is l × W × H
So you do 25 × 11.25 × 6
it equals to 1687.5.
Therefore, the volume of the brick is 1687.5
First compute the coefficient like this:

Simplifying the fraction over 4! we get:

and the variables are

. So answer

.
The correct answer is C then.
17.6 because you do the working out backwards :)
