Bus and underground journeys for the summer months in London are believed to be heavily tied to the number of tourists visiting the city. During the past twelve years the following data has been collected

Summer	Tourists (000,000s)	Journeys (000,000s)
1	7	1.5
2	2	1.0
3	6	1.3
4	4	1.5
5	14	2.5
6	15	2.7
7	16	2.4
8	12	2.0
9	14	2.7
10	20	4.4
11	15	3.4
12	7	1.7
