A bread recipe calls for 3\(\frac{3}{4}\) cups of flour. If you only have \(\frac{1}{4}\) cup, how much more flour is needed?
| 1\(\frac{1}{2}\) cups | |
| 3\(\frac{1}{2}\) cups | |
| 2\(\frac{3}{8}\) cups | |
| \(\frac{1}{4}\) cups |
The amount of flour you need is (3\(\frac{3}{4}\) - \(\frac{1}{4}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{30}{8} \) - \( \frac{2}{8} \)) cups
\( \frac{28}{8} \) cups
3\(\frac{1}{2}\) cups

A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 35% off." If Bob buys two shirts, each with a regular price of $24, how much will he pay for both shirts?
| $8.40 | |
| $39.60 | |
| $25.20 | |
| $32.40 |
By buying two shirts, Bob will save $24 x \( \frac{35}{100} \) = \( \frac{$24 x 35}{100} \) = \( \frac{$840}{100} \) = $8.40 on the second shirt.
So, his total cost will be
$24.00 + ($24.00 - $8.40)
$24.00 + $15.60
$39.60
If there were a total of 50 raffle tickets sold and you bought 2 tickets, what's the probability that you'll win the raffle?
| 1% | |
| 2% | |
| 10% | |
| 5% |
You have 2 out of the total of 50 raffle tickets sold so you have a (\( \frac{2}{50} \)) x 100 = \( \frac{2 \times 100}{50} \) = \( \frac{200}{50} \) = 5% chance to win the raffle.
4! = ?
4 x 3 |
|
3 x 2 x 1 |
|
4 x 3 x 2 x 1 |
|
5 x 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.
