1000.00 at 2.5 percent interest for 4 years<br>

kramer

Answer:

$4100

Step-by-step explanation:

To find the total amount of money, the formula is: principle money × interest rate + 100% × amount of time.

Total amount of money = 1000.00 × $\frac{100+2.5}{100}$ × 4

= 1000.00 × $\frac{102.5}{100}$ × 4

= $4100

If you want to find the interest earned, just deduct the principle amount from the total.

koban [17]

D. Corrine is not correct because Hannah also wins if 6 is on the first cube and 1 is on the second, if 5 is on the first cube and 2 is on the second, and if 4 is on the first cube and 3 is on the second.

Step-by-step explanation:

To get a sum of 7 by rolling two cubes, we need to get one of the combinations from the list below:

1 on the first cube, 6 on the second cube

6 on the first cube, 1 on the second cube

2 on the first cube, 5 on the second cube

5 on the first cube, 2 on the second cube

3 on the first cube, 4 on the second cube

4 on the first cube, 3 on the second cube

Therefore, the correct answer option is D. Corrine is not correct because Hannah also wins if 6 is on the first cube and 1 is on the second, if 5 is on the first cube and 2 is on the second, and if 4 is on the first cube and 3 is on the second.
