Bobby’s football team received four five-yard penalties in the first quarter, which meant his team lost yardage in their progress toward the goal line. If the team started at the 45 -yard line and ended at the 25 -yard line, what was the change in their progression down the field as a result of these penalties?
Each penalty cost the team 5 yards, and there were 4 penalties: 4 × 5 = 20 yards lost. A loss is represented by a negative change, so the change in progression was negative 20 yards.
