Final answer:
The algebraic expression for the number of granola bars each student receives is (5 × 8) ÷ s, with 5 representing the boxes, 8 the granola bars per box, and s the number of students.
Step-by-step explanation:
The algebraic expression that represents how many granola bars each student has after a hike, when a group of s students equally share 5 boxes of granola bars with each box containing 8 granola bars, is given by (5 × 8) ÷ s.
This expression calculates the total number of granola bars by multiplying 5 (the number of boxes) by 8 (the number of granola bars per box) to get the total number of granola bars. T
hen, it divides this total by s, which represents the number of students, to determine how many granola bars each student receives.
