an auto dealer increases the price of a used car 15%. if the new price is $6900, what was the original price of the car

natka813 [3]

Original Price= Markup Price/(1 + markup %)

Original Price= Markup Price/(1 + 15%)

= 6900/(1 + 15%)
change % to decimal

= 6900/(1.15)
divide

= $6,000 original price

ANSWER: The original price before a 15% markup is $6,000.

Hope this helps! :)

Answer:

Option D is correct.

$Volume=\frac{8}{27}\ cubic\ yard$

Step-by-step explanation:

Let V be the volume of hay in each stack

Given:

Length of the each stack is $\frac{2}{3}\ yard$

And Jay stores hay in cubic stacks on his farm.

The volume of the cone is.

$Volume\ of\ cone = (side)^{3}$

Now, we substitute value of length of stack in above equation.

$V=(\frac{2}{3})^{3}$

$V=\frac{2^{3}}{3^{3}}$

$V=\frac{8}{27}\ cubic\ yard$

Therefore, the volume of hay in each stack is $V=\frac{8}{27}\ cubic\ yard$
