Question

The table shows the proportional relationship between the salvage value and tons of raw steel.

Tons of Steel Salvage Value
0 $0
2 $500
4 $1,000
6 $1,500
8 $2,000
10 $2,500

What is the constant of proportionality in terms of salvage value per ton of raw steel?

Answer 1

The constant of proportionality is $250.0 per ton of raw steel.

Here's a breakdown of how we arrived at that answer:

| Tons of steel | Salvage value | Constant of proportionality |

| 0 | $0 | - |

| 2 | $500 | $250.0 |

| 4 | $1,000 | $250.0 |

| 6 | $1,500 | $250.0 |

| 8 | $2,000 | $250.0 |

| 10 | $2,500 | $250.0 |

As you can see, the constant of proportionality (salvage value per ton of raw steel) is always $250.0, regardless of the amount of steel. This means that for every additional ton of steel, the salvage value increases by $250.0.
