oksano4ka [1.4K]

Answer:

73 packs

Given the proportional steel cost, how much do 200 pounds of steel cost?
kotegsom [21]

Answer:

Your answer is B, 150

Step-by-step explanation:

If we look at the chart it says 160 pounds of steel is 120, so for example if we start from 40 we will have 30, so every time we add 40 pounds 30$ are added, meaning that 160+40=200, 120+30= 150, Thus B or 150 is our answer.
