At the movies, you order 3 boxes of popcorn and a bottle of water. the cost of the bottle of water is $1.75. your total cost is $9.25. write and solve an equation to find the cost of one box of popcorn.

3w = $9.25 would be the equation in this case. In order to solve it, you must divide $9.25 by 3. $9.25 / 3 = $3.83 (repeating bar over the second 3). The cost of one box of popcorn is $3.83.

The equation is 1.75+3x=9.25. 1st step is to subtract 1.75 on both sides, which will leave you with 7.5. Divide that by 3 and x=2.5 which means that one box of popcorn costs $2.50

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.
