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
Answer is a. 2
3 - 2x= -7

Answer:
She multiplied the dividend by 100 instead of 10.
Step-by-step explanation:
Ella multiplied the divisor by 10 but mistakenly she multiplied the dividend by 100 instead of 10.
So her division problem changed totally.
Therefore, the correct answer option is B. She multiplied the dividend by 100 instead of 10.
12(3x+4)-5(2x-6)=6x-22
36x + 48 - 10x + 30 = 6x - 22
26x + 48 + 30 = 6x - 22
26x + 70 = 6x - 22
20x + 70 = -22
20x = -92
x = -4.6
