If there were a total of 350 raffle tickets sold and you bought 31 tickets, what's the probability that you'll win the raffle?
| 9% | |
| 8% | |
| 18% | |
| 11% |
You have 31 out of the total of 350 raffle tickets sold so you have a (\( \frac{31}{350} \)) x 100 = \( \frac{31 \times 100}{350} \) = \( \frac{3100}{350} \) = 9% chance to win the raffle.
Roger loaned Diane $1,300 at an annual interest rate of 8%. If no payments are made, what is the total amount owed at the end of the first year?
| $1,365 | |
| $1,326 | |
| $1,404 | |
| $1,391 |
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 = 0.08 x $1,300
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $1,300 + $104
