thank you show work
Let's say that Alicia did x jumping jacks per minute and Margaret did y jumping jacks per minute.
Given that Alicia did 5 more jumping jacks per minute than Margaret, we have the equation:
x = y + 5
Since both Alicia and Margaret did jumping jacks, their rates of jumping jacks per minute must add up to the total number of jumping jacks they did (let's say it was J) per minute:
x + y = J
Substitute the value of x from the first equation into the second equation:
(y + 5) + y = J
2y + 5 = J
2y = J - 5
y = (J - 5) / 2
This equation shows that the rate at which Margaret did jumping jacks is determined by J (total number of jumping jacks both girls did) and is 5 less than half of that total.
Therefore, the correct answer is 1. Margaret did 5 more jumping jacks per minute than Alicia.
