Ahigh interest savings account pays 5.5% interest compounded annually. if $300 is deposited initially and again at the first of each year, which summation represents the money in the account 10 years after the initial deposit

.The amount of $300 is deposited in the account for 10 years from the date of initial deposit.

The Interest rate in the account is 5.5%

Total summation of money in the account after 10 years is given by the following equation = 300 * ((1.055)^10 - 1 ) / 0.055 * ( 1 + 0.055 )

= 300 * (.0.708144)/0.055 * 1.055

= 4075.05

Total money in account after 10 years is $ 4075.05

The Summation sign that can be used to express the equation is

∑3000*(1.055 )^x , where x assumes values from 1 to 10

answer: 1, 3 and 5 are correct

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
