A tiger in a zoo has consumed 60 pounds of food in 5 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 120 pounds?
| 5 | |
| 1 | |
| 4 | |
| 3 |
If the tiger has consumed 60 pounds of food in 5 days that's \( \frac{60}{5} \) = 12 pounds of food per day. The tiger needs to consume 120 - 60 = 60 more pounds of food to reach 120 pounds total. At 12 pounds of food per day that's \( \frac{60}{12} \) = 5 more days.
A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 10% off." If Ezra buys two shirts, each with a regular price of $42, how much money will he save?
| $21.00 | |
| 58 | |
| $16.80 | |
| $4.20 |
By buying two shirts, Ezra will save $42 x \( \frac{10}{100} \) = \( \frac{$42 x 10}{100} \) = \( \frac{$420}{100} \) = $4.20 on the second shirt.
25 members of a bridal party need transported to a wedding reception but there are only 4 5-passenger taxis available to take them. How many will need to find other transportation?
| 5 | |
| 1 | |
| 8 | |
| 4 |
There are 4 5-passenger taxis available so that's 4 x 5 = 20 total seats. There are 25 people needing transportation leaving 25 - 20 = 5 who will have to find other transportation.
If a mayor is elected with 68% of the votes cast and 83% of a town's 42,000 voters cast a vote, how many votes did the mayor receive?
| 20,219 | |
| 26,842 | |
| 18,824 | |
| 23,705 |
If 83% of the town's 42,000 voters cast ballots the number of votes cast is:
(\( \frac{83}{100} \)) x 42,000 = \( \frac{3,486,000}{100} \) = 34,860
The mayor got 68% of the votes cast which is:
(\( \frac{68}{100} \)) x 34,860 = \( \frac{2,370,480}{100} \) = 23,705 votes.
What is \( \frac{1}{7} \) x \( \frac{4}{5} \)?
| \(\frac{1}{18}\) | |
| \(\frac{1}{5}\) | |
| \(\frac{4}{35}\) | |
| \(\frac{1}{42}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{1}{7} \) x \( \frac{4}{5} \) = \( \frac{1 x 4}{7 x 5} \) = \( \frac{4}{35} \) = \(\frac{4}{35}\)
