When we calculate the sum of the series C∞, n=1 ∑ an
whose partial sums are given
sn = 2 − 9(0.9)ⁿ
We can get an answer which is 2.
It has an infinite number of terms, the infinite series. The partial sum is the sum of the first n terms, Sn. The answer in this question is 2.
Answer:
The answer is B
Step-by-step explanation:
y=5x+2, as the slope is 5x, and the y-intercept is 2

Step-by-step explanation:
We must consider the price of the Jeans as whole since it represents the full price of the jeans. The discount might be a limited only offer and does not represent the fullest price of the jeans.
To find the original price of the jeans we have two methods that in the end are going to lead to the same conclusion. The long method is to represent mathematically the information presented. Conceptually, we could interpret the statement saying that the original price minus 30% of the original price is equal to the original price minus the discount. Let us say the Original Price (OP)=x. then, mathematically we represent the statement as:

What we need to do now is to isolate x on one side of the equation. We have x as a common factor, so:



This one is the original price of the jeans: $80. There is a shortcut to this method, though. We know two things that are fundamental: the discount sale is $24 and the jeans are 30% off. These statements provide the same information; thus we can match them and say that:

And we find ourselves on the same conclusion.
Have a wonderful day :D
