Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. Yvonne put $4,000 in a savings account. At the end of 3 years, the account had earned $960 in simple interest.

How much does she have in her account at the end of 3 years?
At what annual simple interest rate did the account grow? Show your work.
How many more dollars would she have in her account if the interest rate were 1% greater? Show your work.

To solve the first question, which is asking for the total amount of money, we have to add what Yvonne started with, with how much she earned.

4,000+960=4,960.

Now for the second question. It is asking for the unit rate of interest earned per year. So we have to divide 960 with the amount of years, which is 3.

960/3=320.

For the last question. 1 percent of 320 is 3.2, so we add 320 with 3.2 to increase the rate. Then we'll multiply the sum with 3 to find how much she would've earned. Finally, we'll add the amount with the 4,000 she started with.

320+3.2=323.2

323.2x3=969.6

4,000+969.6=4,969.6

So the answers are:

How much does she have in her account at the end of 3 years? $4,960

At what annual simple interest rate did the account grow? $320 per year

How many more dollars would she have in her account if the interest rate were 1% greater? 4,969.6

sorry if this doesn't help

step-by-step explanation:

most likely the answer is a.

alice wins if a total of 5 is rolled. finn wins if a total of 9 is rolled.

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!
