Alex loaned Betty $1,500 at an annual interest rate of 5%. If no payments are made, what is the total amount owed at the end of the first year?
| $1,590 | |
| $1,515 | |
| $1,575 | |
| $1,530 |
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 $1,500
i = 0.05 x $1,500
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $1,500 + $75A tiger in a zoo has consumed 40 pounds of food in 8 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 65 pounds?

If the tiger has consumed 40 pounds of food in 8 days that's \( \frac{40}{8} \) = 5 pounds of food per day. The tiger needs to consume 65 - 40 = 25 more pounds of food to reach 65 pounds total. At 5 pounds of food per day that's \( \frac{25}{5} \) = 5 more days.
