Answer:
659
Step-by-step explanation:
We assume the daily rate increases at each multiple of $50. When the balance reaches $50 on day 25, the pay on day 26 is $2.25.
Similarly, when the balance reaches 9628.75 on day 658, the pay will be $50 on day 659.

Slope of -2, y int of 8....
y = -2x + 8
2x + y - 8 = 0 <== general form
Parenthesis first
19- (4+2) - 15 / 3
19-(6)-15 / 3
then division
19-6-5
then subtraction from left to right.
19-6= 13
13-5= 8
your final answer is 8
