Question

Mrs. Murillo purchased three packs of pencils for her art class. Each pack had the same number of pencils (p). She kept five pencils for herself and distributed the remaining pencils equally among the seven students in the class. Which expression represents the number of pencils each student received?

a) (3p + 5)
b) (5 + 1)
c) (5p/7)
d) (3(p + 5)/7)

Answer 1

The expression that represents the number of pencils each student received is (3p - 5)/7.

Step-by-step explanation:

To find the number of pencils each student received, we need to calculate the total number of pencils minus the number of pencils Mrs. Murillo kept. The expression that represents this is (3p - 5) divided by the number of students, which is 7. Therefore, the correct expression is (3p - 5)/7. Option d) (3(p + 5)/7) is incorrect because it includes an extra 5 pencils which were kept by Mrs. Murillo.
