Here is the solution of the given problem above:
Let s= staples
<span>c = chalk</span>
<span>c + 2s = 10 </span>
<span>3c + 2s = 18 </span>
<span>-c-2s = -10 </span>
<span>3c + 2s = 18 </span>
<span>2c = 8 </span>
<span>c = 4 </span>
<span>s = 3
</span>Therefore, the price per chalk box is $4 and per stapler is $3.
So the total cost of the chalk and stapler would be $7.
