Joey has a collection of baseball cards that he has separated into two different value categories. his common cards are worth $0.75 each and his premium cards are worth $2.00 each. together, joey’s entire baseball card collection of 88 cards is worth $106.00. how many cards in joey’s collection are worth $0.75?

56.  I made a table and put the values of x =0.75 and y=2.00 so x+y=88

equation 2:  0.75x+2.00y=106.  Then solve for x!  The answer is 56.

step-by-step explanation:

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.
