Biscuits

Ms. Lopez also sells biscuits in packages.

She uses this ratio table to determine the number of packages she will need for different numbers of biscuits.

  • Complete the ratio table.
  • Make a graph that shows the information in the ratio table.
  • Use the ratio table to find the number of biscuits that will fill 39 packages.

Ask yourself:

  • The second column of the ratio table (with a 1 in the top cell) tells you the number of biscuits in 1 package.
  • Each pair of numbers in the columns of the ratio table represents an ordered pair that defines the coordinates of a point on the graph.
  • How could you add to or subtract from numbers in the table to find the number of biscuits in 39 packages?
