Answer:
Explanation:
Both the equations that you modelled are correct.
Use the substitution method to solve the system of equations

Take the first equation

Now this becomes our third equation and now insert it into our second equation

Now insert R = 223 in any equation. Lets insert it into equation number three

So 223 number of roll papers were sold and 303 number of candles were sold.
I have attached the graph below check it out.
Where both the equations of line intersect is our solution thus we can confirm that our answer is correct.
