The formula for the sum of geometric series = a (1 - r^n) / 1 - r
when it will be an infinite geometric series. the term r^n will equal to zero because and number < 1 that is raise to the power infinity the answer is zero that is why in a infinite geometric series, sum = a / 1 - r.
if the r < 1 then there will be no numerical answer because the sum will be infinity. that is why r < 1 to have a sum
The right answer is Option B.
Step-by-step explanation:
Given,
Purchase price of car with sales tax = $17300
DMV fees = 1.25%
Amount of DMV fees = 1.25% of purchase price
Amount of DMV fees = 
Amount of DMV fees = $216.25
Total price = Purchase price + DMV fees
Total price = 17300 + 216.25
Total price = $17516.25
The total price of car with DMV fees is $17,516.25
The right answer is Option B.
