Question

A) $9 per foot
B) $9.50 per foot
C) $10.00 per foot
D) $10.50 per foot

Answer 1

To find the cost per foot of pipe, divide the total cost of $135 by 15 feet, which equals $9 per foot. Therefore, the correct answer is option A, $9 per foot.

Step-by-step explanation:

The question asks to calculate the cost per foot of pipe given the total cost for a certain length. To find this, we can use the unit rate formula, which is the total cost divided by the number of units (feet, in this case). Here, the total cost is $135 for 15 feet of pipe.

To calculate the cost per foot of pipe:

1. Divide the total cost by the length of the pipe in feet.
2. $135 ÷ 15 feet = $9 per foot.

Therefore, the cost per foot of the pipe is $9, which corresponds to option A.
