A bread recipe calls for 2 cups of flour. If you only have 1\(\frac{1}{8}\) cups, how much more flour is needed?
| \(\frac{7}{8}\) cups | |
| 2\(\frac{3}{8}\) cups | |
| 2\(\frac{5}{8}\) cups | |
| \(\frac{1}{4}\) cups |
The amount of flour you need is (2 - 1\(\frac{1}{8}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{16}{8} \) - \( \frac{9}{8} \)) cups
\( \frac{7}{8} \) cups
\(\frac{7}{8}\) cups
4! = ?
3 x 2 x 1 |
|
5 x 4 x 3 x 2 x 1 |
|
4 x 3 |
|
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.
Alex loaned Charlie $1,100 at an annual interest rate of 9%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $99 | |
| $14 | |
| $126 | |
| $60 |
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 = 0.09 x $1,100
i = $99
A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 50% off." If Alex buys two shirts, each with a regular price of $20, how much money will he save?
| $10.00 | |
| $9.00 | |
| $3.00 | |
| $7.00 |
By buying two shirts, Alex will save $20 x \( \frac{50}{100} \) = \( \frac{$20 x 50}{100} \) = \( \frac{$1000}{100} \) = $10.00 on the second shirt.
