Answer:

Markup = [(Revenue – COGS) / COGS] X 100.

Markup = (Gross Profit / COGS) X 100.

Markup = [(Revenue – COGS) / COGS] X 100.

Markup = [($400 – $250) / $250] X 100.

Selling Price = [(Markup X COGS) + COGS] X 100.

Selling Price = (Markup X COGS) + COGS.

Selling Price = (0.50 X $100) + $100.

A store gives a discount of $20 for every purchase above 100. A customer buys clothes worth $78.04, groceries worth &24.81 a

First figure out his total bill by adding up what he buys.

$\sf 78.04+24.81+17.96=\$120.81$

Now subtract the discount of $20 since his purchase was above $100:

$\sf 120.81-20=\boxed{\sf\$100.81}$

Which expression is equivalent to

True [87]

Answer:

$2^{\frac{5}{12}}$

Step-by-step explanation:

The original expression $\sqrt{2^5} ^{\frac{1}{4}}$ can be transformed into $(2^{\frac{5}{3}})^{\frac{1}{4}}$ : both expressions are equivalent, the root of certain number is equivalent to that number power at a fraction whose denominator is the index of the root. The simpliest example for this statement is $\sqrt{x} =x^{\frac{1}{2}}$ (the squared root of x equals x raised at 1/2).
Now, the expression $(2^{\frac{5}{3}})^{\frac{1}{4}}$ can be simplified by using the power of a power property, which simply states that if $b\neq 0$ and $((b)^n)^m=b^{n\times{m}}$ . In this case, then $(2^{\frac{5}{3}})^{\frac{1}{4}}=2^{\frac{5}{3}\times{\frac{1}{4}}}=2^{\frac{5}{12}}$ , which is the final expression.
