Answer:

The surface area = 548 in²

Step-by-step explanation:

The surface Area = 2lw + 2lh + 2wh  using l = 10 in, w = 7 in, and h = 12in.

Substitute into the formula and solve

  2lw + 2lh + 2wh

= 2· 10·7 + 2· 10 · 12 + 2 ·7 ·12

=  140  +  240 + 168

= 548 in²

Candy is on sale for $0.75 each. you have a coupon for $0.25 off your total purchase. Write a function rule for the cost of n pi
alekssr [168]
<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>
