Pierre and Jen collect badges. Pierre has 3 times as many badges as Jen. This can be shown by p = 3j, where p = the number of badges Pierre owns and j = the number of badges Jen owns. If Pierre has 12 badges, how many does Jen have?

Answer 1

If we substitute p = 12 into the equation p = 3j, we get:

12 = 3j

Dividing both sides by 3:

j = 4

Therefore, Jen has 4 badges.
