There is a 2/10 chance that someone will select the NUMBER 1. You figure this out by seeing how many total triangles are around the circle (10). Then see how many 1's are in the circle (2). Therefore, your probability of selecting the NUMBER 1 is a 2/10 chance.
Answer: First multiply 10 by 20.5 because x represents the number of weeks. You get 205. Next add 165.85 to that and you get 370.85 as your final answer.
