A box of 15 cloud markers cost $12. 70. A box of 42 cloud markers cost $31. 60. How much would a box of 50 cloud markers cost? Write an equation that shows the price, p, for n markers in ab ox. Assume there is no tax, and that the price of a packaging is the same for any size box.

P=0.7N + 2.20
Hope this helps

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
