You are writing a paper for your Finance class and have come across the following information that you will include in your paper as your third graph. The information is concerning nonvideo Toy Sales in England in brick and mortar stores, from 2014-2019, for major stores that increased their advertising budgets by 25% or more over that time period. Quantity (Q) is measured in tens of millions of toys sold and Price (P) is the price of the toy measured in British Pounds. The Wall Street Journal article that included the data was entitled "Selling British Children's Toys While Battling Amazon." The article was written by Bruce Rennert and was published on pages 38-40 in the June 14, 2020 hard copy edition of the paper.
