Answer:

27.83$ I believe

Step-by-step explanation:

30.09 is the end price, so multiply that times 7.5% or 0.075 in decimal terms

You would get 2.25675 which is the amount of tax that was paid

So all you have to left is subtract 2.25675 from 30.09 to find the original price

$30.09-2.25675=27.83325$

or 27.83 rounded to the nearest hundredth

We have x

−ax

+6x−a

Apply remainder theorem

x−a=0

x=a

Put x=a in equation.

(a)

−a(a)

+6a−a

−a

+6a−a

=6a−a

=5a

A solution of salt and water is 20% salt. If 25% of the water is removed, what is the percentage of salt in the new solution?

Ratling [72]

So lets say that this salt and water solution consists of 100 liters.

Then that means 20 liters is salt, and 80 liters out of the 100 is water.

Now, we remove 25% of the water. 25% of 80 liters is 20 liters. So, we are left with 80-20, or 60 liters.

Now in all we have 20 liters of salt, and 60 liters of water.

The percentage of salt in the new mixture will be 20/(20+60) = 20/80 = 25%.

Your answer is 25%
