SOLUTION:

The question says that the cost of 25 cubic meters of flagstone is $350.

This is just a proportional relationship. Thus ;


y=mx,\text{ }b=0

Since the cost of 0 cubic meters of flagstone should be zero.

Thus, lets find m;


\begin{gathered} 350=25m \\ m=14 \end{gathered}

Thus, the amount of flagstone that can be purchased for $500 is;


\begin{gathered} 500=14x \\ x=(500)/(14)=35.7 \end{gathered}

Thus, 500 would fetch us 35.7 cubic meters of flagstone
