Answer:
(-x² + 99x +200)/x
Step-by-step explanation:
Profit per watch = (200 - x)/x
Profit per band = 100 – x
New profit = (200 - x)/x + 100 – x
New profit = (200 - x)/x + x(100 – x)/x
New profit = (200 - x + 100x – x²)/x
New profit = (-x² + 99x +200)/x
A is more because 1/4 is equal to 2/8 and 2/8 is less than 7/8 so you would have more than a minute
B is three minutes 2/8 goes into 7/8 three times
I think it is 0.5 per min
