119. beatrice decides to deposit $100 per month at the end of every month in a bank with an annual interest rate of 5.5% compounded monthly.
a. write a geometric series to show how much she will accumulate in her account after one year.

Beatrice will accumulate $1230.72 at the end of the year.

Step-by-step explanation:

We can write:

for deposits

The first month would have only the deposit reflected in her balance, then, expanding some steps of the calculation would yield:

A geometric series is given by:

Translating our series to the short form:

plugin in the values for the 12 month gives:

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

146%
