Roger loaned Christine $200 at an annual interest rate of 2%. If no payments are made, what is the total amount owed at the end of the first year?
| $202 | |
| $204 | |
| $206 | |
| $210 |
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 $200
i = 0.02 x $200
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $200 + $4If a mayor is elected with 52% of the votes cast and 85% of a town's 15,000 voters cast a vote, how many votes did the mayor receive?
| 10,200 | |
| 9,818 | |
| 10,710 | |
| 6,630 |
If 85% of the town's 15,000 voters cast ballots the number of votes cast is:
(\( \frac{85}{100} \)) x 15,000 = \( \frac{1,275,000}{100} \) = 12,750
The mayor got 52% of the votes cast which is:
(\( \frac{52}{100} \)) x 12,750 = \( \frac{663,000}{100} \) = 6,630 votes.
If the ratio of home fans to visiting fans in a crowd is 4:1 and all 50,000 seats in a stadium are filled, how many home fans are in attendance?
| 31,333 | |
| 40,000 | |
| 33,000 | |
| 20,667 |
A ratio of 4:1 means that there are 4 home fans for every one visiting fan. So, of every 5 fans, 4 are home fans and \( \frac{4}{5} \) of every fan in the stadium is a home fan:
50,000 fans x \( \frac{4}{5} \) = \( \frac{200000}{5} \) = 40,000 fans.
A tiger in a zoo has consumed 63 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 98 pounds?
| 7 | |
| 9 | |
| 5 | |
| 11 |
If the tiger has consumed 63 pounds of food in 9 days that's \( \frac{63}{9} \) = 7 pounds of food per day. The tiger needs to consume 98 - 63 = 35 more pounds of food to reach 98 pounds total. At 7 pounds of food per day that's \( \frac{35}{7} \) = 5 more days.
