Frank loaned April $400 at an annual interest rate of 4%. If no payments are made, what is the total amount owed at the end of the first year?
| $424 | |
| $404 | |
| $416 | |
| $436 |
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 $400
i = 0.04 x $400
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $400 + $16The __________ is the greatest factor that divides two integers.

The greatest common factor (GCF) is the greatest factor that divides two integers.
If a car travels 50 miles in 1 hour, what is the average speed?
| 15 mph | |
| 60 mph | |
| 75 mph | |
| 50 mph |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)Which of the following is not an integer?

An integer is any whole number, including zero. An integer can be either positive or negative. Examples include -77, -1, 0, 55, 119.
Solve 2 + (3 + 5) ÷ 2 x 3 - 42
| \(\frac{1}{4}\) | |
| \(\frac{3}{7}\) | |
| \(\frac{1}{3}\) | |
| -2 |
Use PEMDAS (Parentheses, Exponents, Multipy/Divide, Add/Subtract):
2 + (3 + 5) ÷ 2 x 3 - 42
P: 2 + (8) ÷ 2 x 3 - 42
E: 2 + 8 ÷ 2 x 3 - 16
MD: 2 + \( \frac{8}{2} \) x 3 - 16
MD: 2 + \( \frac{24}{2} \) - 16
AS: \( \frac{4}{2} \) + \( \frac{24}{2} \) - 16
AS: \( \frac{28}{2} \) - 16
AS: \( \frac{28 - 32}{2} \)
\( \frac{-4}{2} \)
-2
