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

Answer:
Original Price = $23
Step-by-step explanation:
$5.75 is the price after a discount of 75%
Let the original price be x and x is 100% of the price
5.75 = 100%x - 75%x
5.75 = 25%x
The new price is 25% of the original because you are subtracting 75%
25% is also written as 0.25
5.75 = 0.25x
x = 5.75/0.25
x = 23
The original price is 23
