I think the answer is D because its multiplying by 2 each time
Judging by the question I generated the equation y=75(1.09^x)
x is the amount of years.
So the equation you should get for 10 years is y=75(1.09^10)
The answer you get should get is $177.55
When factoring, it's easier to "pick out" the GCF first because it makes it simpler to factor even further. Otherwise, you will be troubled with lots of numbers and variables, so it will just get confusing.
N+(n+1) = 85. 2n+1=85, 2n=84. n=42. So the consecutive integers are 42 and 43, and the larger one is 43.
