Maria has thirty songs on her ipod, and each songs costs 1.25. If she downloads 25 and 1/2 of a songs, how much money does she have to spend?

3 is greater then both of those numbers

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.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
