Add those equations together
<span>1. 4x = 16, x = 4
2. Multiple the second one by 2
2x+4y=22
4x-4y=-16
6x = 6, x = 1
3. Add them together
8x = 24, x = 3
</span>
x is the independent variable, and in this scenario, the independent variable is the number of days overdue. So the best equation would be where x is the number of days overdue, and y is the cost in cents.
Example equation:
x = number of days overdue
y = cost in cents
z = total price
z = yx
