To determine the change in yardage from three 15-yard penalties, we can multiply the number of penalties by the yardage of each penalty. In this case, the football team has three 15-yard penalties.

To find the total change in yardage, we multiply 3 by 15:
3 * 15 = 45

Therefore, the real number that describes the change in yardage from these penalties is 45.
