Give the step-by-step reasoning process and then the final answer. Tyson played basketball on the schoolyard. He scored three points fifteen times, and two points twelve times. He also scored one point some number of times. How many times did he score one point, if in total he scored 75 points?
Tyson scored three points fifteen times, which would be 3 * 15 = 45 points. He also scored two points twelve times, which would give him a score of 2 * 12 = 24. So Tyson scored 75 - 45 - 24 = 6 points, by one point each.
The final answer: 6.
