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 $500
i = 0.04 x $500

No payments were made so the total amount due is the original amount + the accumulated interest:

You have 3 out of the total of 50 raffle tickets sold so you have a (\( \frac{3}{50} \)) x 100 = \( \frac{3 \times 100}{50} \) = \( \frac{300}{50} \) = 7% chance to win the raffle.

To add these radicals together their radicands must be the same:

9\( \sqrt{18} \) + 2\( \sqrt{2} \)
9\( \sqrt{9 \times 2} \) + 2\( \sqrt{2} \)
9\( \sqrt{3^2 \times 2} \) + 2\( \sqrt{2} \)
(9)(3)\( \sqrt{2} \) + 2\( \sqrt{2} \)
27\( \sqrt{2} \) + 2\( \sqrt{2} \)

Now that the radicands are identical, you can add them together:

To divide fractions, invert the second fraction and then multiply:

\( \frac{3}{5} \) ÷ \( \frac{4}{8} \) = \( \frac{3}{5} \) x \( \frac{8}{4} \)

To multiply fractions, multiply the numerators together and then multiply the denominators together:

\( \frac{3}{5} \) x \( \frac{8}{4} \) = \( \frac{3 x 8}{5 x 4} \) = \( \frac{24}{20} \) = 1\(\frac{1}{5}\)

44% of the water consumption is industrial use and 12% is personal use so (44% - 12%) = 32% more water is used for industrial purposes. 40,000 gallons are consumed daily so industry consumes \( \frac{32}{100} \) x 40,000 gallons = 12,800 gallons.
