8. The Madison High School Marching Band sold gift wrap to earn money for a band trip. Solid color gift wrap sells for $4 per roll and printed gift wrap sells for $6 per roll. The band needs to earn $2340 for an
upcoming competition. If the band sells 340 rolls of printed paper, write and solve a linear equation to
find the number of solid paper they must sell.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
