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.

Step-by-step explanation:
We require two equations with the recurring part after the decimal point.
let x = 0.2525.... →(1) ← multiply both sides by 100
100x = 25.2525.... → (2)
Subtract (1) from (2) eliminating the recurring decimal, that is
99x = 25 ( divide both sides by 99 )
x =
