The robotics team uses wire to build their robot and controller.

Question

Before building anything, the team has a roll of feet of wire.
To build the robot, the team uses feet of wire.
To build the controller, the team uses foot of wire.

After building, how many feet of wire does the team have left?

A. 2 2/12feet
B. 3 1/12 feet
C. 3 8/12 feet
D. 7 3/12 feet

Answer 1

To find out how many feet of wire the team has left after building the robot and the controller, we can use the following steps:

1. Calculate the total wire used for both the robot and the controller.
2. Subtract this total from the initial amount of wire.

Let's denote:

• \( W \) = total feet of wire the team starts with,
• \( R \) = feet of wire used to build the robot,
• \( C \) = feet of wire used to build the controller.

The total wire used is: \[ \text{Total wire used} = R + C \]

The remaining wire can be calculated as: \[ \text{Remaining wire} = W - (R + C) \]

However, as the specific values for \( W \), \( R \), and \( C \) are not provided in your question, I cannot compute the precise amount of wire left.

Could you please provide the specific amounts of wire used for the robot and the controller, as well as the initial amount of wire? Then I will be able to calculate the remaining amount for you.
