<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

------- + ------- = 0
8 12
In adding fractions.
Step 1: make sure the denominators are the same. 8 and 12 are not the same. But both are factors of 24.
8 * 3 = 24
12 * 2 = 24
Multiply both numerator and denominator of 3/8 by 3 and 5/12 by 2.
3 * 3 5 * 2 9 10
--------- + ------------- = -------- + ---------
8 * 3 12 * 2 24 24
Step 2. Since the denominator is now the same, add the numerator and put it over the denominator.
9 + 10 19
---------- = -------
24 24
Step 3. Simplify the fraction.
19
----
24 is already the simplified form.
