Answer 2

Answer:

The cost of 100 steel posts will be $350.

Solution:

Given that,  

500 steel posts = $1750

Let one steel post cost will be,

Cost of one steel post = $1750 / 500

$\begin{aligned} & = \frac { \ 1750 } { 500 } \\\\ & = \ 3.5 \end{aligned}$

Thus, the cost of one steel post will be $3.5

For 100 steel posts,

Cost of 100 steel posts

$\begin{aligned} = & 100 \times \ 3.5 \\\\ & = \ 350 \end{aligned}$

Hence, the cost of 100 steel posts will be $350.
