The stem-and-leaf plot lists the number of different ingredients found in different industrial cleaners.
how many cleaners had more than 80 ingredients?
enter the answer in the box.

A Stem and Leaf Plot is a special table where each data value is split into a "stem" (the first digit or digits) and a "leaf" (usually the last digit).

Since the key says 4|0= 40 the answer to your question is 12. Twelve cleaners have more than 80 ingredients.

Hope this helps :)
