The sale tax on an item is %6. Express the total cost, C, in terms of the price of the item, P.
skelet666 [1.2K]
<h3>Answer: C = 1.06P</h3>

==========================================================

Explanation:

The sales tax is 6% of the price P

6% of P = 0.06P

Add on the original cost P to get P+0.06P = (1+0.06)P = 1.06P

The 1.06 indicates the final after tax cost is 106% of the original price.

You can think of it like 100% + 6% = 106% = 1.06

So that's how we end up with C = 1.06P

-----------

An example using actual numbers:

Let P = $100 be the initial cost before tax

6% of P = 0.06*P = 0.06*100 = 6 dollars is the tax

100+6 = 106 is the final cost

Note how C = 1.06P = 1.06*100 = 106

Help ASAP!!! Please show all work!!!!!!!
Anastaziya [24]

Answer:

x = 2 and x = -3

Step-by-step explanation:

We need to find the value of x in the below expression.

\sqrt{x+7} -1=x

Adding 1 to both sides,

\sqrt{x+7} -1+1=x+1\\\\\sqrt{x+7}=x+1

Squaring both sides,

x+7=(x+1)^2\\\\x+7=x^2+1+2x\\\\x^2+1+2x-x-7=0\\\\x^2+x-6=0\\\\x=2\ and\ -3

Hence, this is the required solution.

AnnyKZ [126]

Answer:

About $3, 333.30

Step-by-step explanation:

If Karen makes $40,000 a year, that means she makes about $3,333.30 a month (12 months in a year, divide 40,000 by 12 to get the answer) this means she can budget about $3,333.30 a month.

(I rounded to make the answer more realistic the full number is 3333.3333333333333333333333333333)
