Karen has a base salary that is $2100 and does not depends on how many copies she sells.
Additional to the base salary, she gets $50 for each copy she sells, so we can write this additional salary as 50*N, being N the number of copies she sells.
Then, we can write the total pay P as:
Then, if N=22, we can calculate the total pay as:
Answer:
The equation relating P and N is P=2100+50N.
The total pay when she sells 22 copies is $3,200.

Answer:
20%
Step-by-step explanation:
<u><em>Given/To Find:</em></u>
<em>A $52.50 screen door is on</em>
<em>sale for $42. Find the percent</em>
<em>of discount on the door.</em>
<u><em>Solve:</em></u>
<em>Formula: Value 1 - Value 2 ÷ Original Value × 100</em>
<em />
<em>Hence we have:</em>
<em>52.50 - 42 = 10.5</em>
<em>10.5 ÷ 52.50 = 0.20</em>
<em>0.20 × 100</em>
<em>=20%</em>
<em />
<em>Check Answer:</em>
<em>52.50 × 20% = 10.5</em>
<em>52.50 - 10.5 = 42</em>
<em>Hence, the percent of discount on the door is 20%</em>

Answer:
Ok, the rules of the exponent come from a logic construction.
If we have x^n
this means that n is multiplied by itself n times.
If we decompose n into a + b, we have:
x by itself a times, and then x by itself b times, and for how the product works, this is equivalent:
if n = 5, a= 2 and b = 3
x^5 = (x*x*x*x*x) 5 times-
x^5 = x^(2 + 3) = (x^2)*(x^3) = (x*x*)*(x*x*x) = x*x*x*x*x = x^5
And the same for the other rules:
(x^n)^b = x^n*b and such.
Obviusly, this only works when we have a common base.
So the correct answer is that we constructed the exponential rules in a way that only can be used when we have a common base, and this happens because to construct them, we started with common bases.
