The relative percentage is the ratio of a certain outcome compared to the total. In this case the outcome is tails and there were 28 of those. To calculate the percentage you must take the outcome and divide it by the total. If you divide 28 by 70 you get 0.4 meaning the frequency is 40%
Red shirts and blue shirts equally count to his bonus, so he has 15 + 23 = 38 shirts sold at this moment. He needs to sell 75 shirts for the bonus. We subtract our goal from what he have; 75 - 38 = 37.
The strategy here: subtract the goal (75 shirts) from what you did to get to the goal (15 shirts and 23 shirts).
