The percent increase can be calculated using the following formula: Percent Increase = ((New Value - Old Value) / Old Value) x 100 Old Value = 5 laps New Value = 9 laps Percent Increase = ((9 - 5) / 5) x 100 Percent Increase = (4 / 5) x 100 Percent Increase = 0.8 x 100 Percent Increase = 80% Therefore, the percent increase from Mark's first run to his most recent run is 80%.
