Nathan opens a new savings account and makes an initial deposit of $400.

If the account earns 2% annual interest, how much interest will he earn in 9 months?

Brianna takes out a 5-year car loan for $10,000, with an annual interest rate of 4.5%.

Which expression represents the total amount she will pay for the car at the end of the loan?

10,000+10,000(0.045)(5)

10,000(4.5)(5)

10,000(0.045)(5)

10,000+10,000(4.5)(5)

The answer to the first one is 6

Step-by-step explanation:

If the time frame given is 9 months, then we can find that 9 months is 3/4 of a year. 3/4 x 2% = 0.015.     0.015 x 400 = 6. He would have made 6 dollars in 9 months.

Answer the the second one:

4.5% x 5 (years) = 0.225.     0.225 x 10,000 = 2,250. Since this is a car loan and not a bank interest for example, we add it to the total cost. I'm pretty sure its the third one.

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
