21 members of a bridal party need transported to a wedding reception but there are only 4 5-passenger taxis available to take them. How many will need to find other transportation?
| 9 | |
| 1 | |
| 7 | |
| 4 |
There are 4 5-passenger taxis available so that's 4 x 5 = 20 total seats. There are 21 people needing transportation leaving 21 - 20 = 1 who will have to find other transportation.
Charlie loaned Christine $600 at an annual interest rate of 1%. If no payments are made, what is the total amount owed at the end of the first year?
| $654 | |
| $648 | |
| $618 | |
| $606 |
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 $600
i = 0.01 x $600
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $600 + $6If the ratio of home fans to visiting fans in a crowd is 2:1 and all 36,000 seats in a stadium are filled, how many home fans are in attendance?
| 24,800 | |
| 24,000 | |
| 39,167 | |
| 36,000 |
A ratio of 2:1 means that there are 2 home fans for every one visiting fan. So, of every 3 fans, 2 are home fans and \( \frac{2}{3} \) of every fan in the stadium is a home fan:
36,000 fans x \( \frac{2}{3} \) = \( \frac{72000}{3} \) = 24,000 fans.

If \(\left|a\right| = 7\), which of the following best describes a?
none of these is correct |
|
a = 7 or a = -7 |
|
a = -7 |
|
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).
