Answer:

D. 18.68

Step-by-step explanation:

$27\div \frac{5}{3}-6+53\times (\frac{2}{5})^2$

Applying PEMDAS as order of operations.

Solving the exponents first $[(\frac{2}{5})^2=\frac{4}{25}]$

$=27\div \frac{5}{3}-6+53\times \frac{4}{25}$

Multiplying $[53\times \frac{4}{25}=8.48]$

$=27\div \frac{5}{3}-6+8.48$

Dividing $[27\div \frac{5}{3}=16.2]$

$=16.2-6+8.48$

Adding and subtracting.

$=18.68$

Backpack is normally $64.99, put on sale it is marked down to $45.49 what percent off is the sale price

pogonyaev

Answer:

The percent off on the sale price is 30%.

Step-by-step explanation:

Marked up price = $64.99

marked down Price = $45.49

Let us assume the off percentage = k%

Now, the Amount off on the sale = Marked up price - Marked down price

= $64.99 - $45.49 = $19.5

⇒ k% off on Marked up Price $64.99 = $19.5

or, $\frac{k}{100} \times 64.99 = 19.5\\\implies k = \frac{19.5 \times 100}{64.99} = 30$

or, k = 30%

Hence, the percent off on the sale price is 30%
