Betty scored 75% on her final exam. If each question was worth 3 points and there were 120 possible points on the exam, how many questions did Betty answer correctly?
| 36 | |
| 45 | |
| 39 | |
| 30 |
Betty scored 75% on the test meaning she earned 75% of the possible points on the test. There were 120 possible points on the test so she earned 120 x 0.75 = 90 points. Each question is worth 3 points so she got \( \frac{90}{3} \) = 30 questions right.
Roger loaned Betty $600 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?
| $654 | |
| $642 | |
| $612 | |
| $606 |
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 $600
i = 0.02 x $600
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $600 + $12If the ratio of home fans to visiting fans in a crowd is 2:1 and all 49,000 seats in a stadium are filled, how many home fans are in attendance?
| 24,000 | |
| 37,500 | |
| 38,333 | |
| 32,667 |
A ratio of 2:1 means that there are 2 home fans for every one visiting fan. So, of every 3 fans, 2 are home fans and \( \frac{2}{3} \) of every fan in the stadium is a home fan:
49,000 fans x \( \frac{2}{3} \) = \( \frac{98000}{3} \) = 32,667 fans.
14 members of a bridal party need transported to a wedding reception but there are only 3 3-passenger taxis available to take them. How many will need to find other transportation?
| 9 | |
| 8 | |
| 6 | |
| 5 |
There are 3 3-passenger taxis available so that's 3 x 3 = 9 total seats. There are 14 people needing transportation leaving 14 - 9 = 5 who will have to find other transportation.
