A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 5% off." If Alex buys two shirts, each with a regular price of $10, how much money will he save?
| $0.50 | |
| $2.50 | |
| $3.50 | |
| $3.00 |
By buying two shirts, Alex will save $10 x \( \frac{5}{100} \) = \( \frac{$10 x 5}{100} \) = \( \frac{$50}{100} \) = $0.50 on the second shirt.
A tiger in a zoo has consumed 42 pounds of food in 6 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 70 pounds?

If the tiger has consumed 42 pounds of food in 6 days that's \( \frac{42}{6} \) = 7 pounds of food per day. The tiger needs to consume 70 - 42 = 28 more pounds of food to reach 70 pounds total. At 7 pounds of food per day that's \( \frac{28}{7} \) = 4 more days.

The greatest common factor (GCF) is the greatest factor that divides two integers.
A bread recipe calls for 2\(\frac{1}{8}\) cups of flour. If you only have 1\(\frac{1}{2}\) cups, how much more flour is needed?
| \(\frac{5}{8}\) cups | |
| 3\(\frac{1}{8}\) cups | |
| 1\(\frac{3}{4}\) cups | |
| 3\(\frac{5}{8}\) cups |
The amount of flour you need is (2\(\frac{1}{8}\) - 1\(\frac{1}{2}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{17}{8} \) - \( \frac{12}{8} \)) cups
\( \frac{5}{8} \) cups
\(\frac{5}{8}\) cups
