Final answer:
To determine the number of boxes Jen needs for 150 cards with each box holding 6 cards, we divide 150 by 6, which gives us 25 boxes.
Step-by-step explanation:
Jen has to put 180 cards into boxes of 6 cards each. She has already put 150 cards into boxes. To write an equation that could be used to figure out how many boxes Jen needs, we let b stand for the unknown number of boxes.
Since each box contains 6 cards, we can write the equation as:
6b = 150
To find b, we divide both sides of the equation by 6:
b = 150 / 6
b = 25
Therefore, Jen needs 25 boxes to pack the 150 cards.
