Question

Given the proportional steel cost, how much do 200 pounds of steel cost?

Answer 1

$150

Explanation:

Hi,

We know that 160Ibs of steel costs $120. To find the cost of 1Ib of steel, we have to divide both 160Ibs and $120 by 160. Here's what I mean...

Total amount: 160Ibs

Divide by 160...

Total amount: 1Ib

Total cost: $120

Divide by 160...

Total cost: $.75

That means that each pound of steel costs $.75

Now, multiply by 200 to get the total cost if you buy 200Ibs of steel...

200 x .75 = 150

The total cost would be $150

Hope this helps :)

Answer 2

Your answer is B, 150

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.
