A second floor has recently been added to the local public library. There is a team of 8 workers moving crates
of books from the first floor to the second floor. Each
worker can move 32 crates in an hour. For each
additional worker that joins the team, the output of
every worker drops by 2 crates per hour, due to
increased traffic on the elevators and stairways.
What is the maximum possible number of crates that can
be moved per hour?

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.
