Roger loaned Bob $1,500 at an annual interest rate of 8%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $120 | |
| $45 | |
| $4 | |
| $72 |
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 $1,500
i = 0.08 x $1,500
i = $120
A bread recipe calls for 3\(\frac{3}{8}\) cups of flour. If you only have \(\frac{3}{4}\) cup, how much more flour is needed?
| 1\(\frac{5}{8}\) cups | |
| 2\(\frac{5}{8}\) cups | |
| 1\(\frac{1}{2}\) cups | |
| 2\(\frac{3}{4}\) cups |
The amount of flour you need is (3\(\frac{3}{8}\) - \(\frac{3}{4}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{27}{8} \) - \( \frac{6}{8} \)) cups
\( \frac{21}{8} \) cups
2\(\frac{5}{8}\) cups

7 members of a bridal party need transported to a wedding reception but there are only 3 2-passenger taxis available to take them. How many will need to find other transportation?
| 1 | |
| 2 | |
| 7 | |

There are 3 2-passenger taxis available so that's 3 x 2 = 6 total seats. There are 7 people needing transportation leaving 7 - 6 = 1 who will have to find other transportation.
A tiger in a zoo has consumed 45 pounds of food in 9 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 75 pounds?
| 4 | |
| 6 | |
| 9 | |
| 10 |
If the tiger has consumed 45 pounds of food in 9 days that's \( \frac{45}{9} \) = 5 pounds of food per day. The tiger needs to consume 75 - 45 = 30 more pounds of food to reach 75 pounds total. At 5 pounds of food per day that's \( \frac{30}{5} \) = 6 more days.
