5x + 4x²(2x + 7) - 6x² - 9x
5x + 8x³ + 28x² - 6x² - 9x
8x³ + 22x² - 4x
This can be simplified to:
2x(4x² + 11x - 2)
I don't know which of those answers you are looking for.
First, make the equation where x stands for weekly payments.
30x=2730
Then divide both sides by 30.
x= $91
Then multiply $91 by 8 to get how much Hillary meeds to pay altogether at the end of week 8.
91•8=728
So the answer would be $728
20 = 100%
100/20 = 5 (each one represents 5%)
8 * 5 = 40 (40% are chocolate chip)
