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%

What is the value of x in the equation (StartFraction one-half EndFractionx + 12) = StartFraction one-half EndFraction(StartFrac
anastassius [24]

Answer:

x =-24

Step-by-step explanation:

Given

(\frac{2}{3})(\frac{1}{2}x + 12) = (\frac{1}{2})(\frac{1}{3}x + 14) - 3

Required

Solve for x

(\frac{2}{3})(\frac{1}{2}x + 12) = (\frac{1}{2})(\frac{1}{3}x + 14) - 3

Open all brackets

\frac{2}{3}*\frac{1}{2}x + \frac{2}{3}*12 = \frac{1}{2}*\frac{1}{3}x + \frac{1}{2}*14 - 3

\frac{2 * 1}{3 *2}x + \frac{2 * 12}{3}= \frac{1 * 1}{2 * 3}x + \frac{1 * 14}{2} - 3

\frac{1}{3}x + \frac{24}{3}= \frac{1}{6}x + \frac{14}{2} - 3

\frac{1}{3}x +8= \frac{1}{6}x + 7 - 3

Collect like terms

\frac{1}{3}x - \frac{1}{6}x =7 - 3 -8

\frac{1}{3}x - \frac{1}{6}x =-4

Solve fraction

\frac{2-1}{6}x =-4

\frac{1}{6}x =-4

Multiply both sides by 6

6 * \frac{1}{6}x =-4 * 6

x =-4 * 6

x =-24

Answer:

80, 40, 40

Step-by-step explanation:

The rule is if the number before the tens place is 5 or more round up and if it is 4 or less round down.

I like to look at it without the rule and what makes sense.

82.14:  my choices are 80 or 90.  What number is 82.14 closer to on the number line?  80.

38.5  The choices are 30 and 40.  This number on a number line would be closer to 40

41.3  The choices are 40 and 50.  On a number line this number would be closer to 40.
