Answer:
r = 5m
Step-by-step explanation:
miles walked money earned
0 0
1 1*5 5
2 2 * 5 10
3 3 * 5 15
4 4 * 5 20
5 5 * 5 25
6 6 * 5 30
We multiply 5 by each mile walked to determine how much money was raised
r = 5m where r is the money raised and m is the miles walked
Let, the number of cars = x
Then, x*30/100 = 12
x*30 = 1200
x = 1200/30 = 40
so, your answer would be 40
