By buying two shirts, Charlie will save $17 x \( \frac{40}{100} \) = \( \frac{$17 x 40}{100} \) = \( \frac{$680}{100} \) = $6.80 on the second shirt.

So, his total cost will be
$17.00 + ($17.00 - $6.80)
$17.00 + $10.20
$27.20

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

\( \frac{2}{8} \) x \( \frac{2}{5} \) = \( \frac{2 x 2}{8 x 5} \) = \( \frac{4}{40} \) = \(\frac{1}{10}\)

April scored 96% on the test meaning she earned 96% of the possible points on the test. There were 320 possible points on the test so she earned 320 x 0.96 = 308 points. Each question is worth 4 points so she got \( \frac{308}{4} \) = 77 questions right.

Use PEMDAS (Parentheses, Exponents, Multipy/Divide, Add/Subtract):

5 + (3 + 2) ÷ 4 x 3 - 4²
P: 5 + (5) ÷ 4 x 3 - 4²
E: 5 + 5 ÷ 4 x 3 - 16
MD: 5 + \( \frac{5}{4} \) x 3 - 16
MD: 5 + \( \frac{15}{4} \) - 16
AS: \( \frac{20}{4} \) + \( \frac{15}{4} \) - 16
AS: \( \frac{35}{4} \) - 16
AS: \( \frac{35 - 64}{4} \)
\( \frac{-29}{4} \)
-7\(\frac{1}{4}\)

The equation for this sequence is:

a_n = a_n-1 + 4(n - 1)

where n is the term's order in the sequence, a_n is the value of the term, and a_n-1 is the value of the term before a_n. This makes the next number:

a₆ = a₅ + 4(6 - 1)
a₆ = 41 + 4(5)
a₆ = 61
