Ezra loaned Christine $1,100 at an annual interest rate of 3%. If no payments are made, what is the total amount owed at the end of the first year?
| $1,133 | |
| $1,177 | |
| $1,166 | |
| $1,155 |
The yearly interest charged on this loan is the annual interest rate multiplied by the amount borrowed:
interest = annual interest rate x loan amount
i = (\( \frac{6}{100} \)) x $1,100
i = 0.03 x $1,100
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $1,100 + $33The __________ is the greatest factor that divides two integers.

If a car travels 140 miles in 7 hours, what is the average speed?
| 65 mph | |
| 45 mph | |
| 70 mph | |
| 20 mph |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)4! = ?
3 x 2 x 1 |
|
5 x 4 x 3 x 2 x 1 |
|
4 x 3 |
|
4 x 3 x 2 x 1 |
A factorial has the form n! and is the product of the integer (n) and all the positive integers below it. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120.
