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.

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
