The equation is $5^{3}$ × $5^{-2}$

First, you need to solve the bases/exponents

$5^{3}$ is 5×5×5=125

Then you solve the second base/exponent but know that with negative exponents, you divide 1 by the number rather than multiplying

$5^{-2}$ = 1÷5÷5=.04

So now the equation is 125×.04=5

Answer: 5

Cody, the owner of an e-commerce site, buys emerald pendants for $400 and then sells them

Trava [24]

Answer:

The marked up percentage is 112.5%

Step-by-step explanation:

The cost price of the emerald pendant = $400

The selling price of the emerald pendant = $840

Now, the Mark up Price = Selling Price - Cost Price

= $840 - $400 = $450

Also, $\textrm{Percentage of Mark up Price} = \frac{\textrm{the Marked up price}}{\textrm{The Cost Price}} \times 100$

= $\frac{450}{400} \times 100 = 112.5$

⇒ Percentage of Mark up Price = 112.5%

Hence, the marked up percentage is 112.5%
