11 members of a bridal party need transported to a wedding reception but there are only 3 3-passenger taxis available to take them. How many will need to find other transportation?
| 7 | |
| 2 | |
| 9 | |
| 3 |
There are 3 3-passenger taxis available so that's 3 x 3 = 9 total seats. There are 11 people needing transportation leaving 11 - 9 = 2 who will have to find other transportation.
What is (y3)4?

| 3y4 | |
| y-1 |
To raise a term with an exponent to another exponent, retain the base and multiply the exponents:
(y3)4Solve for \( \frac{3!}{4!} \)
| 60480 | |
| \( \frac{1}{4} \) | |
| 5 | |
| \( \frac{1}{7} \) |
A factorial is the product of an integer and all the positive integers below it. To solve a fraction featuring factorials, expand the factorials and cancel out like numbers:
\( \frac{3!}{4!} \)
\( \frac{3 \times 2 \times 1}{4 \times 3 \times 2 \times 1} \)
\( \frac{1}{4} \)
\( \frac{1}{4} \)
A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 25% off." If Frank buys two shirts, each with a regular price of $44, how much will he pay for both shirts?
| $33.00 | |
| $50.60 | |
| $77.00 | |
| $11.00 |
By buying two shirts, Frank will save $44 x \( \frac{25}{100} \) = \( \frac{$44 x 25}{100} \) = \( \frac{$1100}{100} \) = $11.00 on the second shirt.
So, his total cost will be
$44.00 + ($44.00 - $11.00)
$44.00 + $33.00
$77.00
