Answer :
Make a table
X= each day y= amount of money
X/y
0/100
1/96
2/92
3/89
4/85
5/81
6/76
7/72
8/68
9/64
10/60
11/56
12/52
You would need to multiply $4 multiplied by the 12 day which will equal $48. Sence $48 tells the amount of money waisted, you need to subtract $100 - $48 and it will give you $52 .
So the answer is $52
So the answer is $52
