Ms. Houston's fifth-grade class of 20 students is going to a museum.
nydimaria [60]

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
