By buying two shirts, Damon will save $50 x \( \frac{10}{100} \) = \( \frac{$50 x 10}{100} \) = \( \frac{$500}{100} \) = $5.00 on the second shirt.

So, his total cost will be
$50.00 + ($50.00 - $5.00)
$50.00 + $45.00
$95.00

To take the square root of a fraction, break the fraction into two separate roots then calculate the square root of the numerator and denominator separately:

\( \sqrt{\frac{64}{36}} \)
\( \frac{\sqrt{64}}{\sqrt{36}} \)
\( \frac{\sqrt{8^2}}{\sqrt{6^2}} \)
\( \frac{8}{6} \)
1\(\frac{1}{3}\)

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

4\( \sqrt{48} \) - 8\( \sqrt{3} \)
4\( \sqrt{16 \times 3} \) - 8\( \sqrt{3} \)
4\( \sqrt{4^2 \times 3} \) - 8\( \sqrt{3} \)
(4)(4)\( \sqrt{3} \) - 8\( \sqrt{3} \)
16\( \sqrt{3} \) - 8\( \sqrt{3} \)

Now that the radicands are identical, you can subtract them:

If a single cook can bake 2 large cakes per hour and the kitchen is available for 3 hours, a single cook can bake 2 x 3 = 6 large cakes during that time. 29 large cakes are needed for the party so \( \frac{29}{6} \) = 4\(\frac{5}{6}\) cooks are needed to bake the required number of large cakes.

If a single cook can bake 17 small cakes per hour and the kitchen is available for 3 hours, a single cook can bake 17 x 3 = 51 small cakes during that time. 340 small cakes are needed for the party so \( \frac{340}{51} \) = 6\(\frac{2}{3}\) cooks are needed to bake the required number of small cakes.

Because you can't employ a fractional cook, round the number of cooks needed for each type of cake up to the next whole number resulting in 5 + 7 = 12 cooks.

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

\( \frac{1}{9} \) x \( \frac{2}{5} \) = \( \frac{1 x 2}{9 x 5} \) = \( \frac{2}{45} \) = \(\frac{2}{45}\)
