Charlie loaned Roger $1,100 at an annual interest rate of 7%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $91 | |
| $35 | |
| $77 | |
| $56 |
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 = 0.07 x $1,100
i = $77
If there were a total of 50 raffle tickets sold and you bought 4 tickets, what's the probability that you'll win the raffle?
| 8% | |
| 13% | |
| 7% | |
| 18% |
You have 4 out of the total of 50 raffle tickets sold so you have a (\( \frac{4}{50} \)) x 100 = \( \frac{4 \times 100}{50} \) = \( \frac{400}{50} \) = 8% chance to win the raffle.

| b-1 | |
| 3b2 | |
| b5 | |

To raise a term with an exponent to another exponent, retain the base and multiply the exponents:
(b2)3If \(\left|a\right| = 7\), which of the following best describes a?
none of these is correct |
|
a = -7 |
|
a = 7 |
|
a = 7 or a = -7 |
The absolute value is the positive magnitude of a particular number or variable and is indicated by two vertical lines: \(\left|-5\right| = 5\). In the case of a variable absolute value (\(\left|a\right| = 5\)) the value of a can be either positive or negative (a = -5 or a = 5).
