Final answer:
Holly can fold 30 origami boxes in 3 hours, as determined by the given linear equation n = 10t.
Step-by-step explanation:
The student has asked how many origami boxes Holly can fold in 3 hours if the linear equation n = 10t describes n, the number of boxes she can fold in t hours. To find the answer, we simply substitute the value of t with 3 in the equation, which gives us n = 10(3).
The calculation is straightforward:
Therefore, Holly can fold 30 boxes in 3 hours.
