Question

Ms. Houston's fifth-grade class of 20 students is going to a museum.
The class raises $128 for the trip. Transportation to the museum
costs $5 for each student. The museum sells small fossils for $4
each. How many fossils can the students buy with the money they
have left?

1 Answer

  • Answer:

    7 fossils

    Step-by-step explanation:

    Find the cost for transportation by multiplying 20 by 5, since it is $5 per student and there are 20 students

    20(5)

    = 100

    Subtract this from 128, since they raised $128

    128 - 100

    = 28

    This means they have $28 to spend on fossils.

    To find how many they can buy, divide 28 by 4, since they are $4 each

    28/4

    = 7

    So, they can buy 7 fossils with the money they have left
