Estimation Rita goes to the mall. If d is the number of items she bought, the expression 13.95d +21 gives the amount she spent in dollars at one store. Then she spent 22 dollars at another store. Find
the expression which represents the amount Rita spent at the mall. Then estimate how much Rita
spent if she bought 3 items.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
