Monty loaned April $1,300 at an annual interest rate of 3%. If no payments are made, what is the total amount owed at the end of the first year?
| $1,313 | |
| $1,378 | |
| $1,404 | |
| $1,339 |
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 $1,300
i = 0.03 x $1,300
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $1,300 + $39In a class of 23 students, 12 are taking German and 7 are taking Spanish. Of the students studying German or Spanish, 6 are taking both courses. How many students are not enrolled in either course?
| 12 | |
| 10 | |
| 18 | |
| 15 |
The number of students taking German or Spanish is 12 + 7 = 19. Of that group of 19, 6 are taking both languages so they've been counted twice (once in the German group and once in the Spanish group). Subtracting them out leaves 19 - 6 = 13 who are taking at least one language. 23 - 13 = 10 students who are not taking either language.
If there were a total of 150 raffle tickets sold and you bought 4 tickets, what's the probability that you'll win the raffle?
| 6% | |
| 16% | |
| 3% | |
| 12% |
You have 4 out of the total of 150 raffle tickets sold so you have a (\( \frac{4}{150} \)) x 100 = \( \frac{4 \times 100}{150} \) = \( \frac{400}{150} \) = 3% chance to win the raffle.
What is the next number in this sequence: 1, 8, 15, 22, 29, __________ ?
| 36 | |
| 43 | |
| 42 | |
| 40 |
The equation for this sequence is:
an = an-1 + 7
where n is the term's order in the sequence, an is the value of the term, and an-1 is the value of the term before an. This makes the next number:
a6 = a5 + 7
a6 = 29 + 7
a6 = 36
