Chapter 4.3, Problem 16P

If a roll of a certain kind of wrapping paper is unrolled, the wrapping paper forms a rectangle that is 3 feet wide and 20 feet long. The wrapping paper is to be covered with an array of ladybugs by repeating the design shown in Figure 4.25 1. (The arrows and the “3 inches,” “2 inches” are not part of the design; they show the dimensions of a portion of the design.) How many ladybugs will be on the wrapping paper? Explain your reasoning.
